| Product Name | Human Homocysteine (HCY) ELISA Kit |
|---|---|
| Description | Homocysteine is an amino acid with the formula HSCH2CH2CH(NH2)CO2H. It is a homologue of the amino acid cysteine, differing by an additional methylene (-CH2-) group. It is biosynthesized from methionine by the removal of its terminal C_ methyl group. Homocysteine can be recycled into methionine or converted into cysteine with the aid of B-vitamins.Homocysteine is not obtained from the diet. Instead, it is biosynthesized from methionine via a multi-step process. First, methionine receives an adenosine group from ATP, a reaction catalyzed by S-Adenosyl-methionine synthetase, to give S-adenosyl methionine ("SAM"). SAM then transfers the methyl group to an acceptor molecule. The adenosine is then hydrolyzed to yield L-homocysteine. L-homocysteine has two primary fates: conversion via tetrahydrofolate (THF) back into L-methionine or conversion to L-cysteine. This assay has high sensitivity and excellent specificity for detection of Human Hcy. No significant cross-reactivity or interference between Human Hcy and analogues was observed. |
