Description

        The kit uses anti BSA antibody as the coating antibody, the enzyme labeled anti BSA antibody as the detection antibody, the highly sensitive TMB as the substrate, and the BSA as the standard to quantitatively detect BSA in the sample. This kit is characterized by good specificity, high sensitivity and stability,

        The lowest detectable level of BSA is 0.1ng/ml.   

Principle

        This kit uses double antibody sandwich method to detect BSA residuals. The BSA antibody is coated on the microplate, and the BSA in the sample or standard is combined with the antibody fixed on the microplate. After the unconjugated sample or standard is washed with washing solution, the HRP-labeled BSA antibody is added for incubation, and the enzyme labeled antibody is combined with BSA. Wash the unconjugated enzyme labeled antibody, add TMB substrate solution to the microplate, incubate it in dark to form a blue complex, stop the reaction with stop solution, and the color changes from blue to yellow. Determine the absorbance value of the complex, and fit the standard curve with the OD value of the standard. The BSA concentration of the sample can be calculated from the OD value of the sample through the formula fitted with the standard curve.

Kit components

Specificity

        Antibody-coated plate, HRP labeled antibody and BSA standards are stored at -20℃, other components are stored at 2-8℃. It is stable for 6 months.
