Product Overview:
E1136Ge is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the A Disintegrin and Metalloprotease 30 (Cysteine) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing Cysteine. The ELISA analytical biochemical technique of the E1136Ge kit is based on Cysteine antibody-Cysteine antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect Cysteine antigen targets in samples. The ELISA Kit is designed to detect native, recombinant, Cysteine. Appropriate sample types may include undiluted human body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Cysteine and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

General Annotation


Sub Unit:
N/A


Function:
Cysteine (abbreviated as Cys or C) is an α-amino acid with the chemical formula HO2CCH(NH2)CH2SH. It is a semi-essential amino acid, which means that it can be biosynthesized in humans. Its codons are UGU and UGC. Cysteine was considered to be a hydrophilic amino acid based on the belief that the thiol group interacts well with water. However, the cysteine side chain participates in the hydrophobic bonding system of the micelle. The quantitative comparison of the values of the critical micelle concentrations leads to the conclusion that the CH2SH group of amino acid has the same effect on the micelle stability as a methylene group of the hydrocarbon tail. Therefore, there is justification for the recently voiced assumptions of the hydrophobic nature of the cysteine side chain in proteins. The thiol side chain often participates in enzymatic reactions, serving as a nucleophile. The thiol is susceptible to oxidization to give the disulfide derivative cystine, which serves an important structural role in many proteins. When used as a food additive, it has the E-number E920.
