WebBiotin quantitative labeling: biotin with optimized structure and chromophore group can be quantified after labeling. Essential Information Molecular weight 810.92 Excitation/Absorption maximum (nm) 354 Emission maximum (nm) 509 Molar extinction coefficient ε (L⋅mol−1⋅ cm−1) 29000 Correction coefficient of 280nm(CF280) 0.29 WebHABA Calculator. HABA is a dye with absorbance and avidin-binding properties that help enable the quantitation of biotin in a sample. When HABA is bound to avidin, the complex absorbs light at 500 nm (e = 34,000/M cm). When a biotin-containing sample is added, the biotin binds strongly to avidin and displaces the weakly bound HABA resulting in ... cheap flights from okc to sfo
