Protein Labeling Kits Products & Reviews

IRDye 680LT dye is highly soluble in water and is significantly brighter and more photostable than many other 700 nm near-infrared dyes.

Biotinylated Hyaluronan Binding protein (b-HABP) (versican G1 domain, VG1)

Label your antibody with one of our superior CF ®  Dyes in 15 minutes without a purification step. Labeling tolerates many common buffer components including BSA and ascites.

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.

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.

Activation of ICE-family proteases/caspases initiates apoptosis in mammalian cells. Chemicon's Caspase-3 Colorimetric Activity Assay Kits provide a simple and convenient means for assaying the activity of caspases that recognize the sequence DEVD. The assay is based on spectophotometric detection of the chromophore p-nitroaniline (pNA) after cleavage from the labeled substrate DEVD-pNA. The free pNA can be quantified using a s…

DNA methylation was the first epigenetic modification identified and has been intensively studied for more than half a century. By now it is clear that Dnmt1, the major eukaryotic DNA methyltransferase, faithfully maintains genome-wide methylation patterns and plays an essential role in the epigenetic network controlling gene expression and genome stability during development. However, the molecular mechanisms that ultimately…
