In breast cancer STC2 is induced by estrogen and STC2 expression levels correlate with levels of estrogen receptor. STC2 function in different cancers may involve regulation of cell proliferation, neoplastic transformation and endothelial invasion. STC2 also plays a role in epithelial-mesenchymal transition by activation of MAPK/ERK signaling in hypoxic ovarian cancer cells.

Collagen-induced arthritis (CIA) in mice is widely used as an experimental model for rheumatoid arthritis (RA) in humans. CIA is mediated by autoantibodies, which bind to a particular region of type II collagen, such as CB11 (CNBR-digested fragment of type II collagen) (Terato et al, 1985). Antibody-mediated CIA can be induced by i.v. injection of a combination of four different monoclonal antibodies generated by the ArthroMAB…

CHEMICON's Actin Cytoskeleton and Focal Adhesion Staining Kit is a very sensitive immunocytochemical tool that contains fluorescent-labeled phalloidin (TRITC-conjugated phalloidin) to map the local orientation of actin filaments within cell and a mouse monoclonal antibody to Vinculin that is very specific for the staining of focal contacts in cells.

The TRAPEZE® ELISA Kit provides the reagents necessary for performing the TRAP assay followed by ELISA detection of telomerase activity in cell/tissue samples.

The Amplifluor™ UniPrimer™-fluorescein is a hairpin primer labeled with a fluorescent energy transfer pair (fluorescein and non-fluorescent quencher) and a 3' single-stranded oligonucleotide tail and is provided at a concentration of 5.0 μM (25.0 mL).

GST fusion-protein, corresponding to the p21-binding domain (PBD, residues 67-150) of human PAK-1 provided bound to glutathione agarose. Specifically binds to and precipitates Rac-GTP and cdc42-GTP from cell lysates.

GST-tagged fusion protein, corresponding to residues 7-89 of mouse Rhotekin Rho Binding Domain, expressed in E.coli and bound to glutathione-agarose. Specifically binds to and precipitates GTP-Rho, but not GDP-Rho from cell lysates.

For use to immunoprecipitate transcriptionally active chromatin from mammalian cells using anti-Acetyl-Histone H4, ChIP grade rabbit antiserum.

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 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.

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. This assay uses the downstream effector of Rac/Cdc42, p21-activated protein kinase (PAK1), to isolated the active GTP-bound form of Rac/Cdc42 from the sample. The p21 binding domain (PBD) of PAK1 is expressed as a GST-fusion protein and coupled to agarose beads. After precipitation, an immunoblot is performed and…
