Tri-methyl Lysine Antibody (pan specific), HRP
Catalog#
Product Description
ICP0602
This rabbit polyclonal antibody is isolated and affinity purified from the anti-serum against chemically methylated protein antigen. The affinity purified trimethylated lysine antibodies are affinity absorbed with N-(epsilon) mono- and di-methylated lysine. The purified antibody is conjugated to horse radish peroxidase (HRP) via reductive amination. Direct labelling of primary antibodies will avoid the use of secondary antibodies therefore eliminating the effects of the secondary antibody-conjugates. The antibodies could be utilized for detection and quantization of proteins with N-trimethylated lysine residues.

Scientific Description
In the biosynthetic pathway of 1-carnitine, epsilon-N-trimethyllysine hydroxylase is the first enzyme that catalyzes the formation of beta-hydroxy-N-epsilon-trimethyllysine from epsilon-N-trimethyllysine. This reaction is dependent on alpha ketoglutarate, Fe2+, and oxygen.
Storage & Stability
Product is stable for several weeks at 4°C. For extended storage, and store product at -20°C. Expiration date is six months from date of shipping if stored properly.
