WebMar 14, 2009 · You can also use the method with solutions prepared in you own lab, much cheaper if you plan many determinations. The method, together with a protein determination (A280, BCA etc) will give you a value for the degree of biotinylation (mole biotin:mole protein). From this you can obtain an approximation of the conc of your biotinylated protein. WebRather, after labeling, the biotin molar substitution ratio is measured directly by a simple UV-spectrophotometric scan (220–420 nm) or single point measurements at two wavelengths (A280/A354). Alternatively, a single wavelength (A354) can be used in combination with a protein assay (e.g., BCA or Bradford) to quantify the molar …
