I am working on a multi-site clinical study and one of our study sites is in India. Blood samples from participants have been collected and stored at -80 in PAXgene blood RNA tubes. The study is nearing completion and I need to arrange for the blood samples (~1000 samples) to be shipped somewhere where RNA extraction can be performed and then a subset will need to undergo RNA-seq. Most of the companies who do RNA-seq will only accept RNA and they do not provide RNA extraction as a service so I will probably need to get the extraction done separately with a different service provider.
