Principle of the Assay: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for CBS has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any CBS present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CBS is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CBS bound in the initial step. The color development is stopped and the intensity of the color is measured.

NCBI Description

The protein encoded by this gene acts as a homotetramer to catalyze the conversion of homocysteine to cystathionine, the first step in the transsulfuration pathway. The encoded protein is allosterically activated by adenosyl-methionine and uses pyridoxal phosphate as a cofactor. Defects in this gene can cause cystathionine beta-synthase deficiency (CBSD), which can lead to homocystinuria. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, May 2010]

Uniprot Description

Function: Only known pyridoxal phosphate-dependent enzyme that contains heme. Important regulator of hydrogen sulfide, especially in the brain, utilizing cysteine instead of serine to catalyze the formation of hydrogen sulfide. Hydrogen sulfide is a gastratransmitter with signaling and cytoprotective effects such as acting as a neuromodulator in the brain to protect neurons against hypoxic injury

Catalytic activity: L-serine + L-homocysteine = L-cystathionine + H2O.

Cofactor: Pyridoxal phosphate.

Enzyme regulation: Allosterically activated by adenosyl-methionine (AdoMet).

Product Notes

The Human CBS cbs (Catalog #AAA700623) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA700623 ELISA Kit recognizes Human CBS. It is sometimes possible for the material contained within the vial of "cystathionine-beta-synthase, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
