Triton is a trademark of The Dow Chemical Company. From the obtained data, it is not easy to decide which method is the most accurate in determining venom protein concentration, as we do not know its true value. The main components of venom include proteins, with and without enzymatic activity, and peptides. Also, as in the Bradford assay, you determine your protein concentration by creating a standard curve from a known, standard protein. Linearization of the Bradford protein assay increases its sensitivity: theoretical and experimental studies. On the other hand, in the case of studies concerning venoms with similar compositions, that decision could be of less importance. Protein standards were prepared as described above covering a suitable concentration range for the assay. Because it is the bradford reagent was sterile, bradford assay is not?
