RNA-protein UV-crosslinking Assay
Authors:  Dipak Kumar Poria and Partho Sarothi Ray, date: 03/20/2017, view: 13189, Q&A: 2
RNA-protein interactions play a crucial role in every aspect of RNA metabolism, and also plays a major role in post-transcriptional gene regulation. RNA-binding proteins have been implicated in viral gene expression (Ray and Das, 2002) and ...
Polysome Analysis
Authors:  Dipak Kumar Poria and Partho Sarothi Ray, date: 03/20/2017, view: 13570, Q&A: 1
Polysome analysis is a method to separate mRNAs from a cell into actively translating and non-translating fractions depending on their association with polysomes. By this protocol, cell lysates are fractionated by sucrose density gradient ...
