• Benefits: The Quick ELISA kits, assay takes less than 1.5 hours. Detect Human CST3 with <10pg/ml sensitivity. Format: 96-well plate with removable strips.; This is a TMB colorimetric sandwich ELISA kit with short assay time and quick experiment set up.
• Principle: Human CST3 Pre-Coated ELISA (Enzyme-Linked Immunosorbent Assay) kit is a solid phase immunoassay specially designed to measure Human CST3 with a 96-well strip plate that is pre-coated with mouse monoclonal antibody specific for CST3. The detection antibody is a HRP linked goat polyclonal antibody specific for CST3. The kit contains recombinant Human CST3 with immunogen: Expression system for standard: NS0; Immunogen sequence: M1-A146. The kit is analytically validated with ready to use reagents.; ; To measure Human CST3, add standards and samples to the wells, then add HRP linked detection antibody. Wash the wells with PBS or TBS buffer, and add TMB. TMB is substrate to HRP and will be catalyzed to produce a blue color product, which changes into yellow after adding acidic stop solution. The density of the yellow product is linearly proportional to Human CST3 in the sample. Read the density of the yellow product in each well using a plate reader, and benchmark the sample wells' readings against the standard curve to determine the concentration of Human CST3 in the sample.
• Assay Procedure Step 1: 20000pg/ml, 10000pg/ml, 5000pg/ml, 2500pg/ml, 1250pg/ml, 625pg/ml, 312.5pg/ml
• TMB Incubation Time: 15
• Preparation and Storage: Store at 4 degree C for 6 months, at -20 degree C for 12 months. Avoid multiple freeze-thaw cycles. (Shipped with wet ice.)

Application Data

Related Product Information for CST3 elisa kit

Cystatin C or cystatin 3(formerly gamma trace, post-gamma-globulin or neuroendocrine basic polypeptide), a protein encoded by the CST3 gene, was originally described as a constituent of normal cerebrospinal fluid(CSF) and of urine from patients with renal failure. 1 Cystatin 3 has a low molecular weight(approximately 13. 3 kilodaltons), and it is removed from the bloodstream by glomerular filtration in the kidneys. In humans, all cells with a nucleus(cell core containing the DNA) produce cystatin C as a chain of 120 amino acids. It is found in virtually all tissues and bodily fluids. Cystatin C, which belongs to the type II cystatin gene family, is a potent inhibitor of lysosomal proteinases2(enzymes from a special subunit of the cell that break down proteins) and probably one of the most important extracellular inhibitors of cysteine proteases3(it prevents the breakdown of proteins outside the cell by a specific type of protein degrading enzymes). Moreover, cystatin C is involved in network reorganization in the epileptic dentate gyrus. 4
