详细描述:
生物素OSu通过赖氨酸残基与DNP-BSA偶联。
Biotin OSu is conjugated to DNP-BSA through lysine residues.
Properties:
Appearance: yellow powder;
Absorption Maximum (Lambda Max): 360;
Extinction Coefficient at Lambda max: 17400;
Product Usage:
Conjugation for the DNP is determined at 360 nm using 1.74 x 10E+04 as the extinction coefficient of DNP and is given as a molar ratio of DNP to BSA assuming the molecular weight of BSA is 66,430. Store solution in aliquots at -20°C. Protect from light. This product can be dissolved in water or phosphate buffered saline (PBS) pH 7.2 at a concentration of 1 mg/mL. Product may precipitate when stored in solution, therefore it is recommended to centrifuge the solutions briefly before use and use only the supernatant. When using PBS please refer to the formulation below. PBS Formulation: 8 g NaCl 0.2 g KCl 0.2 g potassium di-hydrogen phosphate (KH2PO4) 1.15 g di-sodium hydrogen phosphate (Na2HPO4) Add to 1 L of water;
Storage and Handling:
Shipping Conditions: Ambient;
