WebUse the following formula for a path length of 1 cm. Concentration is in mg/ml, %, or molarity depending on which type coefficient is used. concentration = Absorbance at 280 nm divided by absorbance coefficient. To convert units, use these relationships: Mg protein/ml = % protein divided by 10 = molarity divided by protein molecular weight. WebMar 31, 2011 · Scientists frequently use Bovine Serum Albumin (BSA) to address both the issue of non-specific binding and stability. When BSA is added to an immunoassay it binds to sites where there is potential for non-specific binding without interfering with antibody/antigen binding. An added bonus of using BSA is that it stabilizes proteins while …
