This video demonstrates the enhanced crosslinking immunoprecipitation (eCLIP) method for identifying RNA-binding proteins in mouse testis. eCLIP enables the precise identification of binding sites where RNA-binding proteins (RBPs) interact with their target RNAs.

Chromatin Immunoprecipitation

Histones are proteins that help organize DNA in eukaryotic nuclei by serving as “scaffolds” around which DNA can be wrapped, forming a complex called “chromatin”. These proteins can be modified through the addition of chemical groups, and these changes affect gene expression. Researchers use a technique called chromatin immunoprecipitation (ChIP) to better understand which DNA regions associate with specific histone modifications or other gene regulatory proteins. Antibodies are used to isolate...

Here, we present a protocol to enrich endogenous RNA binding sites or "footprints" of RNA:protein (RNP) complexes from mammalian cells. This approach involves two immunoprecipitations of RNP subunits and is therefore dubbed RNA immunoprecipitation in tandem (RIPiT).

Co-Immunoprecipitation and Pull-Down Assays

2023
Co-immunoprecipitation (CoIP) and pull-down assays are closely related methods to identify stable protein-protein interactions. These methods are related to immunoprecipitation, a method for separating a target protein bound to an antibody from unbound proteins. In CoIP, an antibody-bound protein is itself bound to another protein that does not bind with the antibody, this is followed by a separation process that preserves the protein-protein complex. The difference in pull-down assays is that...

This method can be used to measure RNA synthesis. 5-Bromouridine is added to cells and incorporated into synthesized RNA. RNA synthesis is measured by RNA extraction immediately after labelling, followed by 5-Bromouridine-targeted immunoprecipitation of labelled RNA and analysis by reverse transcription and quantitative polymerase chain reaction.
FAQs
The antibody determines which RNA-binding protein serves as the molecular entry point for recovery. When the target protein is present in a cell lysate, its associated complexes can be retained through antibody binding, allowing the co-purified RNA to reflect interactions connected to that protein. Consequently, antibody choice focuses the experiment on a particular post-transcriptional regulatory network rather than on RNA molecules generally.
Protein A or G beads act as the physical capture support for antibody-bound protein complexes. Their role links the molecular recognition provided by the antibody to recovery of the associated RNA from the lysate. Because the beads are part of the capture stage, they connect target-protein selection with subsequent RNA isolation and analysis.
RNA immunoprecipitation can examine messenger RNA together with noncoding RNA, so the experiment is not limited to protein-coding transcripts. Associations recovered with a selected RNA-binding protein can provide evidence relevant to RNA stability, localization, translation, or processing. This range makes the technique useful for tracing several forms of post-transcriptional regulation within biology.
Once antibody-bound complexes have been captured, the associated RNA is isolated rather than inferred only from the presence of the protein. Researchers can then analyze that material by RT-qPCR or sequencing. The resulting RNA profile links a selected RNA-binding protein with particular RNA molecules, helping characterize post-transcriptional regulatory interactions.
By identifying RNAs associated with a selected RNA-binding protein, RNA immunoprecipitation can show which post-transcriptional interactions are relevant during cellular responses. Researchers may use these associations to connect protein-RNA regulation with changes in RNA stability, localization, translation, or processing. This makes the technique useful for investigating how cells regulate gene expression in response to biological conditions.
It is useful when researchers need to relate RNA-binding protein interactions to disease mechanisms or RNA-based therapeutic targets. The associated RNA molecules can help define regulatory relationships that may become important in disease-related biology. In this context, RNA immunoprecipitation provides a way to investigate protein-RNA interactions as part of broader molecular studies.
