  • RNA storage and shipping for Illumina seq

    Hello!
    I need to send some samples to USA for mRNA seq. Since I can't prepare the cDNA here, I need to send the RNA. I thought to precipitate it and then send at 4°C. Anybody has never done this? Or anybody has alternative options?
    Moreover, someone knows which carrier is the best in mRNA precipitation (acrylamide or glycogen)?? Can they interfere with the following protocol?
    Many thanks

    The best will be to send total RNA in 0.1M soduim acetate and 2 vol ethanol. I used to send total RNA to US for Affymetrix and Exiqon microarray experiments.

    Hope this helps

      If you have not already extracted your RNA, you can also lyse the samples in Trizol and ship the samples while frozen in Trizol. If the other lab is unable to perform a precipitation, you can also use RNAStable to store your sample. Your samples can then be shipped without dry ice and rehydration is as simple as adding water. The protocol is a bit more complicated for you, but it's much easier for the end user.

        Hi! Which brand produce RNA stable? Do you know if it has been used for RNA for Illumina seq?

          Hi Narendra!
          I need to follow up the protocol until the mRNA purification from rRNA, since the purification hasn't been paid to the seq facility... Do you know if the same way could be good also for mRNA? And do you meant shipping it in solution of sodium acetate and ethanol, without pelleting? At wich temperature did you ship?

            RNA Stable is produced by a company called Biomatrica. We've used it before to send total RNA, mRNA, and even small RNA for Illumina RNA library generation and didn't have any issues.

              Hello,

              Has anyone else have use RNAstable, what are your experiences with this product?

              Thanks

              Kind regards

                Our facility has used the RNA stabilization product from Gentegra with success. Samples are shipped at room temperature and remain stable. Upon arrival the RNA is resuspended and suitable for downstream applications such as an RNA-Seq library.

                Innovative saliva collection products for COVID-19 testing and Active chemical protection to keep DNA & RNA stable during shipping.

                  What is the cost per sample for GenTegra-RNA?

                    The cost through the US distributor is ~$4.00 per sample. There are 96-well plate options that reduce per sample cost below $2.00.

                      Current Approaches to Protein Sequencing
                      by seqadmin


                      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

                      Strategies for Sequencing Challenging Samples
                      by seqadmin


                      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
