Other notes

Small volumes of Total Protein Assay Kit vials may occasionally become trapped in the product vial seal during shipping and storage. If necessary, briefly spin the vial in a tabletop centrifuge to dislodge any liquid in the vial cap. Certain products may require dry ice shipping and an additional dry ice fee may apply.

Product related information for The Total Protein Assay Kit

Assay principle: Cu2+ can be reduced to Cu+ by protein under alkaline conditions. Cu+ can combine with the BCA reagent and form a purple complex, which has a maximum absorption peak at 562 nm. The OD value is proportional to the protein concentration. The protein concentration can be calculated indirectly based on the OD value at 562 nm.
