Application Notes
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 600nm; the Cys content is calculated by the absorbance at 600nm.

Principle of the Assay: Cys accumulates in large amounts on the surface of the skin and mucous membranes, maintains the activity of important sulfhydryl enzymes during keratin production, and supplements sulfhydryl groups to maintain the normal metabolism of the skin and regulate the underlying melanin produced by the pigment cells in the lowermost layer of the epidermis. It has the functions of whitening, detoxification, improving inflammation and allergic skin. 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.
Background/Introduction: 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.

Product Notes
The Cys (Catalog #AAA9719028) is an Assay Kit and is intended for research purposes only. The product is available for immediate purchase. 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 600nm; the Cys content is calculated by the absorbance at 600nm. Researchers should empirically determine the suitability of the Cys for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Cysteine (Cys), Assay 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.Precautions
