1 Before You Begin Procedural Notes

Procedural Notes

10 S

Certain protocol steps require the rapid transfer of sample plates between the Bravo deck and a thermal cycler. Locate your thermal cycler in close proximity to the Agilent NGS Workstation to allow rapid and efficient plate transfer.

Use of Agilents SureCycler 8800 thermal cycler and associated plasticware is recommended for optimal performance. The workflow is compatible with additional thermal cyclers, but performance should be validated before running a large number of samples. See page 30 for a list of supported PCR plate types and ensure that the thermal cycler to be used is compatible with one of the supported PCR plate types.

Prepare and load the Agilent NGS Workstation as detailed in each of the protocol steps before initiating each automated protocol run. When loading plates in the workstations Labware MiniHub, always place plates in the orientation shown in Figure 4 on page 37.

To prevent contamination of reagents by nucleases, always wear powder- free laboratory gloves and use dedicated solutions and pipettors with nuclease- free aerosol- resistant tips.

Avoid repeated freeze- thaw cycles of stock and diluted RNA and cDNA solutions. Possible stopping points, where samples may be stored at 20C, are marked in the protocol. Do not subject the samples to multiple freeze/thaw cycles.

When preparing master mix reagent stock solutions for use:

1 Thaw the reagent vial as rapidly as possible without heating above room temperature.

2 Mix thoroughly on a vortex mixer at high speed for 5 seconds, then briefly spin in a centrifuge to drive the contents off of walls and lid.

3 Store vials used during an experiment on ice or in a cold block.

4 Library Preparation Master Mixes should not be frozen and thawed more than five times. If you plan to use the reagents in more than five experiments, aliquot to multiple vials to minimize freeze/thaw cycles for each vial.

In general, follow Biosafety Level 1 (BL1) safety rules.

Experimental Setup Considerations for Automated Runs

28 S

Agilent SureSelect Automated Strand- Specific RNA Library Prep runs may include 1, 2, 3, 4, 6, or 12 columns (equivalent to 8, 16, 24, 32, 48, or 96 wells) of RNA samples to be prepared for sequencing on the Illumina platform. Plan your experiments using complete columns of samples.

The number of columns or samples that may be processed using the supplied reagents will depend on the experimental design. For greatest efficiency of reagent use, plan experiments using at least 3 columns per run. Each 96- reaction kit contains sufficient reagents for 96 reactions configured as 4 runs of 3 columns of samples per run.

Considerations for Placement of RNA Samples in 96-well Plates for Automation

SureSelect Automat

The Agilent NGS Workstation processes samples column- wise beginning at column 1. RNA samples should be loaded into 96- well plates column- wise, in well order A1 to H1, then A2 to H2, ending with A12 to H12. When processing partial runs with <12 sample columns, do not leave empty columns between sample columns; always load the plate using the left- most column that is available.

For sample indexing by PCR (see Figure 2), you will need to prepare a separate plate containing the indexing primers. Assign the wells to be indexed with their respective indexing primers during experimental design.

Considerations for Equipment Setup

Some workflow steps require the rapid transfer of sample plates between the Bravo deck and a thermal cycler. Locate your thermal cycler in close proximity to the Agilent NGS Workstation to allow rapid and efficient plate transfer.

Several workflow steps require that the sample plate be sealed using the PlateLoc thermal microplate sealer included with the Agilent NGS Workstation, and then centrifuged to collect any dispersed liquid. To maximize efficiency, locate the centrifuge in close proximity to the Agilent NGS Workstation.

PCR Plate Type Considerations

30 S

Automation protocols include several liquid- handling steps in which reagents are dispensed to PCR plates in preparation for transfer to a thermal cycler. For these steps you must specify the PCR plate type to be used on the SureSelect_RNA_ILM.VWForm to allow correct configuration of the liquid handling components for the PCR plate type. Before you begin the automation protocol, make sure that you are using a supported PCR plate type. The PCR plate type to be used in the protocol is specified using the menu below.

This section contains instructions for RNA library preparation specific to the Illumina paired- read sequencing platform and to automated processing using the Agilent NGS Workstation.

For each sample to be sequenced, individual library preparations are performed in separate wells of a 96- well plate. The samples are then indexed by PCR amplification allowing multiplexing of up to 48 samples for sequencing on Illumina platforms.

Refer to Illuminas protocol Preparing Samples for Paired- End Sequencing (p/n 1005361), or the appropriate Illumina protocol for more information.

In this step, automation protocol mRNA_Purification_v1.0.pro is used to complete multiple steps of the RNA Library Preparation workflow. First, poly(A) RNA is purified from total RNA using two serial rounds of binding to oligo(dT) magnetic particles. After purification, the poly(A) RNA is chemically- fragmented to the appropriate size and then is converted to first- strand cDNA.

Total RNA samples containing 50 ng to 4 g RNA are suitable for the mRNA library preparation automation protocol. Each total RNA sample must be prepared for the run in 25 L of nuclease- free water.

NOTE For optimal performance, total RNA samples should have an RNA Integrity Number (RIN) of 8 or more, based on analysis using Agilents 2100 Bioanalyzer.

Consider preparing an additional sequencing library in parallel, using a high- quality control RNA sample, such as Agilent QPCR Human Reference Total RNA (p/n 750500). Use of this control is especially recommended during the first run of the protocol, to verify that all protocol steps are being successfully performed. Routine use of this control is helpful for any required troubleshooting, in order to differentiate any performance issues related to RNA input from other factors.

A workstation operator must be present during this automation protocol to transfer plates between the workstation, which completes most liquid handling steps, and the thermal cycler, which is used for several incubation steps. In addition, the operator must prepare and dispense a master mix immediately before it is used in the automation protocol (see step 30 on page 48).

Step 8. Pool samples for multiplexed sequencing

SureSelect Automat

The number of indexed libraries that may be multiplexed in a single sequencing lane is determined by the output specifications of the platform used, together with the amount of sequencing data required for your research design. Calculate the number of indexes that can be combined per lane, according to the capacity of your platform and the amount of sequencing data required per sample.

1 Combine the libraries such that each index- tagged sample is present in equimolar amounts in the pool. For each library, use the formula below to determine the amount of indexed sample to use.

Volume of Index V f C f # C i

--------------------------------=

where V(f) is the final desired volume of the pool,

C(f) is the desired final concentration of all the DNA in the pool

# is the number of indexes, and

C(i) is the initial concentration of each indexed sample.

Table 47 shows an example of the amount of 4 index- tagged samples (of different concentrations) and Low TE needed for a final volume of 20 L at 10 nM.

2 Adjust the final volume of the pooled library to the desired final concentration.

Table 47 Example of indexed sample volume calculation for total volume of 20 L

Component V(f) C(i) C(f) # Volume to use (L)

Sample 1 20 L 20 nM 10 nM 4 2.5

Sample 2 20 L 10 nM 10 nM 4 5

Sample 3 20 L 17 nM 10 nM 4 2.9

Sample 4 20 L 25 nM 10 nM 4 2

Low TE 7.6

3 Sample Preparation Step 8. Pool samples for multiplexed sequencing

84 S

If the final volume of the combined index- tagged samples is less than the desired final volume, V(f), add Low TE to bring the volume to the desired level.

If the final volume of the combined index- tagged samples is greater than the final desired volume, V(f), lyophilize and reconstitute to the desired volume.

3 If you store the library before sequencing, add Tween 20 to 0.1% v/v and store at - 20C short term.

Exact library pool dilution and processing can vary based on the flow cell capacity and analysis pipeline versions being used. Refer to the appropriate Illumina user guide for instructions.

Proceed to cluster amplification using the Illumina Paired- End Cluster Generation Kit; refer to the manufacturers instructions for this step. The optimal seeding concentration for cluster amplification from SureSelect mRNA libraries is approximately 10- 12 pM.

NOTE The optimal seeding concentration may vary, depending on the method used for library quantification and fragment size distribution.

This protocol has been validated with 2 x 100- base paired- end reads. However, read length can be adjusted to achieve the desired research goals.

Sequencing run setup guidelines for 8-bp indexes

Sequencing runs must be set up to perform an 8- nt index read. For the HiSeq platform, use the Cycles settings shown in Table 48. Cycle number settings can be specified on the Run Configuration screen of the instrument control software interface after choosing Custom from the index type selection buttons.

For complete index sequence information, see the Reference chapter starting on page 87.

Sequence analysis guidelines

The SureSelect RNA sequencing library preparation method preserves RNA strandedness using dUTP second- strand marking. The sequence of read 1, which starts at the P5 end, matches the reverse complement of the poly- A RNA transcript strand. Read 2, which starts at the P7 end, matches the poly- A RNA transcript strand. When running analysis of this data to determine strandedness, it is important to include this information. For example, when using the Picard tools (https://broadinstitute.github.io/picard) to calculate RNA sequencing metrics, it is important to include the parameter STRAND_SPECIFICITY= SECOND_READ_TRANSCRIPTION_STRAND to correctly calculate the strand specificity metrics.
