For use to immunoprecipitate transcriptionally active chromatin from mammalian cells using anti-acetyl-Histone H3

A GST-tagged fusion protein, corresponding to residues 7-89 of mouse Rhotekin Rho Binding Domain, expressed in E. coli. Provided bound to glutathione-agarose. Purity 90%.

Anti-cdc42 is a mouse monoclonal IgG1 that recognizes cdc42 from human, mouse, rat and dog

This non-radioactive kinase assay kit is a two-stage peptide phosphorylation/colorimetric detection assay kit. In the first stage, a biotinylated substrate peptide containing tandem repeats of Poly (Glu4-Tyr) is incubated with a tyrosine kinase enzyme sample in the presence of non-radioactive ATP and a Mn2+/Mg2+ co-factor cocktail. The kinase assay can be performed with substrate peptide either in solution, or bound to the wel…

This kit contains nonradioactive components for radiolabeling and purifying histone H4 peptide with [3H]-acetyl CoA. The radiolabeled peptide is a suitable substrate for assay of HDAC activity. HeLa nuclear extract, which is rich in histone deacetylase activity, is included as a positive control. The HDAC inhibitor sodium butyrate is provided to demonstrate specificity of the deacetylase activity.

Accessory reagent kit for the analysis of histone methyltransferase activity.

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 fluorometric substrate. Next, Activator Solution releases a fluorophore from the deacetylated substrate or standard.

This kit is designed to measure the phosphotransferase activity in a kinase cascade reaction initiated by activated Raf-1. Recombinant unactive MEK1 is the substrate for Raf-1. Once activated by Raf-1, MEK1 can phosphorylate and thereby activate another kit component, recombinant unactive MAP Kinase 2/Erk2. Activation of MAP Kinase 2/Erk2 is determined by phosphorylation of myelin basic protein (MBP), in vitro. Phosphorylation…

The assay kit is designed to measure B-Raf dependent phosphotransferase activity in a kinase cascade reaction using recombinant MEK1, unactive as a B-Raf substrate. Recombinant MAPK2/Erk2, unactive is phosphorylated and activated by the activated MEK1 leading to phosphorylation of a MAP Kinase substrate, myelin basic protein (MBP). [γ-32P]ATP is the final phosphate donor.
