Folic Acid/Vitamin B9 (FA/VB9) Detection Kit

Use: Used to detect the concentration of folic acid/vitamin B9 (FA/VB9) in samples such as serum, plasma, and cell culture supernatant.Specificity: The kit uses enzyme-linked immunosorbent assay. Biotin-labeled folic acid/vitamin B9 (FA/VB9) and purified anti-folic acid/vitamin B9 (FA/VB9) antibodies are coated on microplates. In the competitive inhibition reaction, a certain amount of solid-phase antibody and biotin-labeled folic acid/vitamin B9 (FA/VB9) and non-labeled antigen (calibrator or specimen) inhibit the competitive reaction. The binding amount of antibody and biotin-labeled folic acid/vitamin B9 (FA/VB9) is inhibited by the amount of non-labeled antigen. The more non-labeled antigen, the less binding of antibody and biotin-labeled folic acid/vitamin B9 (FA/VB9), and vice versa. After the reaction is balanced, solid-phase antibody-biotinylated folic acid/vitamin B9 (FA/VB9) is formed, and then enzyme-labeled avidin is added to form a solid-phase antibody-biotinylated folic acid/vitamin B9 (FA/VB9)-enzyme label-avidin complex. After adding substrate for color development, the absorbance (OD value) is measured at a wavelength of 450nm using an enzyme reader. As the concentration of folic acid/vitamin B9 (FA/VB9) increases, the OD value gradually decreases and shows a good linear relationship. This kit has the characteristics of high sensitivity, strong specificity, good repeatability, simple operation and rapidity, and has reliable detection performance for the reduction or increase of folic acid/vitamin B9 (FA/VB9) in samples.
