The reverse primer of the instant invention incorporates a poly-T120 for a poly-A120 in the mRNA. Other reverse primers with longer or shorter poly(T) tracts can be used to adjust the length of the poly(A) tail in the mRNA.

The reaction is cleaned up using Invitrogen's PURELINK™ PCR Micro Kit (Carlsbad, Calif.) per manufacturer's instructions (up to 5 μg). Larger reactions will require a cleanup using a product with a larger capacity. Following the cleanup, the cDNA is quantified using the NANODROP™ and analyzed by agarose gel electrophoresis to confirm the cDNA is the expected size.

Whole Transcriptome Profiling of S1P and VM Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Whole transcriptome libraries from two S1P pools and two VM replicates were produced using MicroPolyA Purist Kit (Ambion) and SOLiD Total RNA-Seq kit (Applied Biosystems). Briefly, approximately 200 ng/sample poly (A)-positive RNA was enriched using MicroPoly (A) Purist Kit from 15–20 μg total RNA. Quality and concentration of the extracted poly (A)-positive RNA was re-assessed as described above, and poly (A)-positive RNA was digested with RNase III. Ligation of the adaptor mix and reverse transcription was performed following the manufacturer instructions. cDNA libraries were size selected for 150–250 bp fragments, amplified in 15–18 PCR cycles using barcoded adaptor primers and purified with PureLink PCR micro kit (Invitrogen). These barcoded cDNA libraries were then amplified by emulsion PCR from 0.5 pM template. Sequencing beads from the barcoded libraries were pooled and loaded on a SOLiD 4 slide (Applied Biosystems), according to manufacturer’s instructions. SOLiD ToP Sequencing chemistry was used to produce pair end (50 bp + 35 bp) sequencing reads.

Small RNA-Seq Library Preparation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
20 ng of EV RNA and 120 ng cell RNA, both enriched for small RNA, was used as the starting input for RNA-Seq library preparation. The preparation of the cDNA library was done according to the protocol from Applied Biosystems SOLiD™ small RNA library preparation from Invitrogen. The cDNA fragments were barcoded in the PCR amplification step to enable simultaneous sequencing of different samples in a single run. The cDNAs underwent 18 cycles of PCR using barcoded primers. The PCR products were purified using PureLink™ PCR Micro Kit (Invitrogen) and analyzed for size and concentration on Agilent 2100 Bioanalyzer using DNA HS chips. Equal molar amount of each barcoded sample were pooled together in one library, which subsequently were used in emulsion PCR to a total concentration of 0.5 pM. Approximately 1 billion enriched beads were deposited on a full glass slide for SOLiD 5500xl sequencing. Cell RNA from Hs578T and AU565 was previously sequenced on SOLiD4 [42 ], SRA accession SRX273660 (AU565) and SRX273750 (Hs578T). All sequencing was performed at the genomic facility, Nord University. Raw sequences were submitted to the National Center for Biotechnology Information (NCBI) Short Read Archive, Bioproject PRJNA309295

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
