PRODUCT INFORMATION TNP-BSA-Biotin Base Catalog No.: T-5055

Base Catalog No.: T-5055
Biotin OSu is conjugated to 2,4,6-Trinitrophenyl-Bovine Serum Albumin. This product is homologous to TNP-BSA.
Chemical Name: 2,4,6-Trinitrophenyl-Bovine Serum Albumin-Biotin
Appearance: yellow to orange powder
Absorption Maximum (Lambda Max): 348 nm
Extinction Coefficient at Lambda max: 15400/M/cm
Product Usage
Conjugation is determined at pH 7.0 by measuring TNP absorbance at 348 nm using 1.54 x 10E+04 as the extinction coefficient of
TNP and is given as a molar ratio of TNP to BSA assuming the molecular weight of BSA is 60,000. The spectral properties listed for
this product are the properties of the hapten and not of the hapten-carrier conjugate. The biotin moiety is not quantified.
Store solution in aliquots at -20°C. Protect from light.
