Chromatin Immunoprecipitation (ChIP) is an important technique allowing the researcher to analyze in vivo interactions of proteins with genomic DNA. Any chromatin-associated or DNA binding protein can be analyzed with this technique, provided a good antibody to the protein exists. One can measure different proteins localized to a specific region of the genome, or the genome wide distribution of a specific protein. Another powe…
The 384 well format kit is a newer version of the tried and true non-radiographic HDAC assay. As in the previous kit, samples are first incubated with the HDAC Assay substrate, allowing deacetylation of the fluorometric substrate. After incubation, the activator solution is added, and releases a fluorophore from the deacetylated substrate or standard. The sample is then put into a microplate reader and fluorescence (i.e free/c…
This assay is a simple two-step procedure performed in a microtiter plate. In the first step, samples are incubated with the HDAC assay substrate, allowing deacetylation of the substrate. Next, the Activator Solution releases p-nitroanilide from the deacetylated substrate or standard.
The EZ-Zyme™ Chromatin Prep kit allows ChIP analysis at nucleosome resolution by performing complete or partial digestions with a proprietary enzymatic cocktail to obtain chromatin fragments of on average one to a few nucleosomes in length. Compared to sonication, this procedure not only allows mapping the protein-DNA association at a higher resolution, but also renders the subsequent immunoprecipitation more efficient due to…
The Rac1/Cdc42 Activation Assay provides an effective method for detecting Rac and Cdc42 activity in cell lysates.
