HNMT Human, actief

Source: Escherichia Coli.Sterile Filtered clear colorless solution.Histamine N-Methyltransferase or HNMT, is located in the cell cytosol. Sadenosyl-L-methionine acts as a methyl donor for HNMT which inactivates histamine. By inactivation of histamine, it affects the immune systemâ€TMs response. HNMT acts on histamine in body tissues such as kidney, central nervous system and bronchus. The protein has a crucial part in the airway response to histamine & histamine degradation process and regulation.HNMT Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 328 amino acids (1-292 a.a) and having a molecular mass of 37.4kDa. HNMT is fused to a 36 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

HMT, HNMT-S1, HNMT-S2, MRT51.

Functional Assay

Greater than 90.0% as determined by SDS-PAGE.

HNMT protein solution (1mg/mL) containing 20mM, Tris-Hcl (pH8.0) and 10% glycerol.

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please avoid freeze-thaw cycles.

Specific activity is > 200 nmol/min/mg, and is defined as the amount of enzyme that transfer 1.0 nmole of methyl group per minute at 37°C.
