Human BAFF/CD257 (B-Cell Activating Factor) ELISA Kit
The Human BAFF (B Cell Activating Factor) ELISA Kit is a powerful tool for researchers looking to accurately measure BAFF levels in human samples such as serum, plasma, and cell culture supernatants. With exceptional sensitivity and specificity, this kit delivers reliable and reproducible results for a variety of research applications.BAFF, also known as CD257, is a key cytokine that plays a critical role in B cell survival, proliferation, and maturation. Dysregulation of BAFF has been linked to autoimmune diseases such as lupus and rheumatoid arthritis, making it a valuable biomarker for studying these conditions and developing targeted therapies.
By utilizing the Human BAFF ELISA Kit, researchers can gain valuable insights into the role of BAFF in immune system function and disease pathology, ultimately advancing our understanding of autoimmune disorders and facilitating the development of innovative treatments.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human BAFF/CD257. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human BAFF/CD257 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 Human BAFF/CD257, 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 Human BAFF/CD257. You can calculate the concentration of Human BAFF/CD257 in the samples by comparing the OD of the samples to the standard curve.
