RNA Binding Protein Immunoprecipitation (RIP) Service

RNA Binding Protein Immunoprecipitation (RIP) Service

Immunoprecipitation (IP)-based techniques are one of the key techniques to study the interaction between proteins and other macromolecules, such as Co-IP (Co-immunoprecipitation) to study protein-protein interactions, RIP (RNA binding protein immunoprecipitation assay) to study protein-RNA interactions, and ChIP (chromatin immunoprecipitation assay) to study protein-DNA interactions.

RIP technology mainly uses antibodies against target proteins to precipitate the corresponding RNA-protein complexes, which can be separated and purified for q-PCR validation or sequencing analysis of the RNA bound to the complexes.  RIP is a technique to study intracellular RNA-protein binding, and its application fields include post-transcriptional regulation studies and epigenetic regulation. RNA-binding proteins (RBPs) are involved in the transcription and maturation of mRNAs, including biological processes such as processing, translocation, stabilization, degradation and translation; similarly, some mRNA molecules are regulated by ribonucleoprotein complexes (RNPs) at the post-transcriptional level ; RIP is a powerful tool to understand the dynamic processes of post-transcriptional regulatory networks and can help discover the regulatory targets of miRNAs.

RIP Applications

a) Use of antibodies or epitope tags to capture endogenous RBPs in the nucleus or cytoplasm.

b) Preventing the binding of non-specific RNAs.

c) Immunoprecipitation to isolate RBPs together with their bound RNAs.

d) The bound RNA sequences are identified by quantitative RT-PCR or high-throughput sequencing (RIP-Seq) methods.

RIP Features

RIP can reflect the interaction between RNA and protein in the natural cellular state;

Identify RNAs that directly/indirectly interact with RBPs

RIP-q-PCR verifies the proteins screened by RNA pull down-MS to avoid false positives.
