Methylated Lysine Antibody, HRP

Catalog # Pack Size Price(USD)
ICP0502 100 μg $375.00


Product Description
The affinity purified rabbit polyclonal anti-methylated lysine antibody was developed using a technique unique to ImmuneChem. The methylated lysine antibodies are affinity purified using N-methyl (epsilon amino group) lysine on agarose as the affinity matrix. The purified antibody was conjugated to horse radish peroxidase (HRP) via reductive amination. Direct labelling of primary anti-MeK will avoid the use of secondary antibodies therefore eliminating the interference of the secondary antibody-conjugates. The antibodies could be utilized for detection, quantization and isolation of proteins with MeK residues.
Western blot analysis of the methylated protein pattern in whole HeLa cells with ICP0502.

Methylated KLH conjugates
Methyl-lysine and di-methyl lysine on agarose
Reductive amination; HRP/Ab molar ratio - 10:1
Anti-MeK peroxidase conjugates recognize proteins methylated on their lysine residues (mono and di-methyllysine). They do not cross react with acetylated proteins.
Scientific Description
MeK is a conserved post-translational modification and is an important biochemical process for many protein-protein interactions. It is found in many proteins, for example calmodulin, cytochrome C, chromosomal proteins, histones and non-histones as well as neural storage body proteins. It has been suggested that methylation of lysine plays an important role in gene silencing. [1-3]
