详细描述：
4-羟基-3-硝基苯基乙酰基半抗原通过酰胺键与BSA（牛血清白蛋白）蛋白赖氨酸偶联。
4-Hydroxy-3-nitrophenylacetyl hapten is conjugated to BSA (Bovine Serum Albumin) protein through lysine by amide bonds.
Properties:
Appearance: yellow powder;
Absorption Maximum (Lambda Max): 430;
Extinction Coefficient at Lambda max: 4230;
Product Usage:
Conjugation is determined at pH 8.5 by measuring NP absorbance at 430 nm, using 4.23 x 10E+03 as the extinction coefficient of NP, and is given as a molar ratio of NP 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;
Storage Conditions: +2 to +8 °C
