ChIRP Assay

Date: 2018-01-24 Author: Leading Biology Click: 1115

Introduction

ChIRP, also called Chromatin Isolation by RNA Purification, is a method based on affinity capture of target IncRNA (long non-coding RNA)-Chromatin complex, which then generates a map of genomic binding sites at a resolution of several hundred bases with high sensitivity and low background.


There are many advantages of ChIRP assay, first, it could identify the binding sites anywhere on the genome, second, it enables the discovery of new binding sites, last but not least, it allows the selection of specific RNA. ChIRP is applicable to many IncRNAs because the design of affinity-probes is straightforward given the RNA sequence and requires no knowledge of the RNA’s structure or functional domains.


ChIRP Assay



Procedures:
1. Chromatin was cross-linked to lncRNA: protein adducts in vivo.
2. Biotinylated tiling probes were hybridized to target lncRNA, and the complexes are purified using magnetic streptavidin beads.
3. The lncRNA bound DNA or proteins was eluted by a cocktail of RNase A and H.

4. Extracted DNA fraction from ChIRP samples was identified by sequencing or quantitate by qPCR.
