Check to see if BioRad bovine serum albumin (BSA) Protocol works with oyster tissue link to BSA protocol if it does, use the results from the assay run to calculate total protein concentration per sample (ug/mL) I am going to want to use various dillutions of the samples so I can get the protein concentration in the linear range (<2000 ug/mL) [Read More]
