A sandwich ELISA kit for quantitative measurement of Rat CTLA4 (Cytotoxic T-Lymphocyte Associated Antigen 4) in samples from Serum, Plasma, Cell supernatant

• Additional information:Gentaur's CTLA4 ELISA kit utilizes the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat CTLA4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat CTLA4 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat CTLA4, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat CTLA4. You can calculate the concentration of Rat CTLA4 in the samples by comparing the OD of the samples to the standard curve.
• Storage and shipping:The kit is shipped on ice packs or blue ice. Upon receving it, keep refrigerated at 1 to 8 degress Celsius. The shelf life of this is guaranteed to be at least 6 months from the date of receipt.
• Notes:This Rat CTLA4 ELISA kit is intended for research use only. Do not use for human or animal diagnostics.
