Cysteine Assay Kit

 

 

소개 (Description)

Cysteine (Cys) is the only sulfur-containing amino acid with a sulfhydryl group, an important structural and functional amino acid of proteins, which is synthesized from homocysteine in animals. Cys participates in the formation of protein disulfide bonds and it is often a component of the active center of enzymes. It also provides sulfhydryl groups for other biological reactions.

 

Cys can be accumulated in large amounts on the skin and mucous membranes to maintain normal metabolism of the skin during keratin and melanin production. Cys is also involved in several redox pathways and it is a precursor of glutathione. Low levels of Cys have been related to damage from reactive oxygen species (ROS), while high levels have been related to several cardiovascular and metabolic diseases.

 

BQC Cysteine Assay Kit is a quick, easy, and reproducible assay to quantify cysteine content in a wide variety of samples.

 

 

 

 

 

 

분석 원리 (Assay Principles)

This assay is based on the reduction of phosphotungstic acid by Cys to produce tungsten blue. The concentration of this blue compound can be measured at 600 nm and is proportional to the Cys content in the sample.
