详细描述：
与氨基DEXTRAN偶联的NP（4-羟基-3-硝基苯基乙酸）半抗原。偶联作为每分子DEXTRAN的NP给出，并且通过在430nm处的NP吸光度确定，假设DEXTRAN MW为500,000。
NP (4-Hydroxy-3-nitrophenylacetic) hapten conjugated to Amino DEXTRAN. Conjugation is given as NPs per molecule of DEXTRAN and is determined by NP absorbance at 430 nm, assuming DEXTRAN MW of 500,000.
Properties:
Chemical Name: 4-Hydroxy-3-nitrophenylacetyl DEXTRAN;
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 430nm, using the extinction coefficient of NP= 4.23 x 10E+03. The conjugation ratio is given as a molar ratio of NP to DEXTRAN assuming the molecular weight of DEXTRAN is 500,000. Store solution in aliquots at -20°C. Protect from light. This product can be dissolved in PBS buffer, water or other neutral buffers at a concentration of 1mg/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.
