BCA

BCA (Bicinchoninic Acid) assay kits are widely used for total protein quantification in biological samples. These colorimetric assays provide high sensitivity and compatibility with detergents, making them ideal for measuring protein concentration in cell lysates, purified protein preps, or biomanufacturing workflows. Compared to Bradford or Lowry assays, BCA offers superior linearity and low protein-to-protein variability. It is commonly used in Western blot normalization, ELISA sample prep, and protein yield measurement following extraction or purification. Wasteless Bio offers access to unopened, surplus BCA kits, including both microplate and tube formats. Listings include detection range, sample compatibility, and reaction conditions, allowing for precise protein quantification with minimized waste and procurement cost.
