The bicinchoninic acid assay bca assay also known as the smith assay after its inventor paul k. This water soluble complex exhibits a strong absorbance at 562 nm that is nearly linear with increasing protein concentrations over a broad working range 20 2000 µg ml. When using multiwell plates make sure the unknown samples.
