Disassociate the RNA from the protein of interest. Isolate the RNA fragments from the protein using a centrifuge. Use Reverse Transcription PCR to convert the RNA fragments into cDNA (DNA that is complementary to the RNA fragments). Fluorescently label these cDNA fragments. Prepare the gene chip. This is a small chip that has DNA sequences ...
Cross-linking and immunoprecipitation (CLIP, or CLIP-seq) is a method used in molecular biology that combines UV crosslinking with immunoprecipitation in order to identify RNA binding sites of proteins on a transcriptome-wide scale, thereby increasing our understanding of post-transcriptional regulatory networks.
Immunoprecipitation of intact protein complexes (i.e. antigen along with any proteins or ligands that are bound to it) is known as co-immunoprecipitation (Co-IP). Co-IP works by selecting an antibody that targets a known protein that is believed to be a member of a larger complex of proteins.
Jill recently shared a cooking hack video that includes a fun and easy science project for kids that can be done in your own kitchen!. In the video, Jill starts by grabbing a glass of water and a ...
iCLIP [1] [2] [3] (individual-nucleotide resolution crossLinking and immunoprecipitation) is a variant of the original CLIP method used for identifying protein-RNA interactions, [4] which uses UV light to covalently bind proteins and RNA molecules to identify RNA binding sites of proteins.
RNA partitions in the aqueous phase, while proteins and DNA partition into the organic/interphase (left). The RNA is then precipitated in an alcohol (right). Acid guanidinium thiocyanate-phenol-chloroform extraction (abbreviated AGPC ) is a liquid–liquid extraction technique in biochemistry and molecular biology .
DNA:RNA In Vitro Enrichment (DRIVE-seq): [1] This method shares very similar principles of DRIP-seq except for the use of MBP-RNASEH1 endonuclease instead of the S9.6 mAb for R-loops recovery. MBP-RNASEH1 provides an alternative to S9.6 mAb when an additional capture assay is needed, however over-expression of this endonuclease may introduce ...
Salting out (also known as salt-induced precipitation, salt fractionation, anti-solvent crystallization, precipitation crystallization, or drowning out) [1] is a purification technique that utilizes the reduced solubility of certain molecules in a solution of very high ionic strength.
