ACCPA (Anti-Cyclic Citrullinated Peptide Antibody) (ACCPA) ELISA Kit for Human

Intended Uses: This ELISA kit applies to the in vitro quantitative determination of Human ACCPA concentrations in serum, plasma and other biological fluids.

Principle of the Assay: This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antigen specific to ACCPA. Standards or samples are added to the appropriate micro ELISA plate wells and combined with the specific antigen. Then a biotinylated detection antigen specific for ACCPA and Avidin-Horseradish Peroxidase (HRP) conjugate is added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain ACCPA, biotinylated detection antigen and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid 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 ACCPA.You can calculate the concentration of ACCPA in the samples by comparing the OD of the samples to the standard curve.

Small volumes of ACCPA elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS2505320 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the ACCPA (anti-cyclic citrullinated peptide antibody) 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 ACCPA. The ELISA analytical biochemical technique of the MBS2505320 kit is based on ACCPA antibody-ACCPA antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect ACCPA antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, ACCPA. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).
