CheKine™ Micro Cysteine (Cys) Assay Kit

Protein contains three sulfur-containing amino acids: methionine, cystine and Cys. Among them, Cys is the only sulfur-containing amino acid containing a sulfhydryl group, which is converted from methionine and can be mutually converted with cystine. Cys participates in the formation of protein disulfide bonds and is often a component of the active center of proteins. It can also provide sulfhydryl groups for other physiological and biochemical reactions.

• Determination of Cys conten in a variety of biological samples such as Liquid sample, plant tissues, cells, and bacteria. • Detailed sample preparation and result calculation methods are provided. • Simple operation steps. • Standard and standard curve line are provided.

The kit provides a simple method for detecting the Cys conten in a variety of biological samples such as Liquid sample, tissues, cells, and bacteria. Cys reduces phosphotungstic acid to produce tungsten blue, which has an absorption peak at 600 nm; the Cys content is calculated by the absorbance at 600 nm.

• Do not mix or substitute reagents or materials from other kit lots or vendors. • Avoid foaming or bubbles when mixing or reconstituting components. • Avoid cross-contamination, change pipette tips between additions of standards, samples and reagents. Also, use separate reservoirs for each reagent. • Ensure all reagents and equipment are at the appropriate temperature before starting the assay.
