Recombinant Human CXCL13/BCA-1 (E. coli) 别名：CXC chemokine BLC; Small-inducible cytokine B13; 重组人CXCL13/BCA-1蛋白 (E. coli)
CXCL13, also known as B-lymphocyte chemoattractant (BLC), is a CXC chemokine that is constitutively expressed in secondary lymphoid organs. Recombinant human CXCL13 is a single non-glycosylated polypeptide chain containing 87 amino acids and mature human BCA-1 shares 64 % amino acid sequence similarity with the murine protein and 23–34 % amino acid sequence identity with other known CXC chemokines. Determined by a chemotaxis bioassay using human B cells, the biological activity is in a concentration range of 1.0-10 ng/ml.

实验参考
建议您制定动物给药及实验方案时，尽量参考已发表的相关实验文献（溶剂种类及配比众多，简单地溶解目的化合物，并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题，未必能保证目的化合物在动物体内充分发挥生物学效用）。
体内实验的工作液，建议您现用现配，当天使用；如在配制过程中出现沉淀、析出现象，可以通过超声和（或）加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中，输入您的动物实验相关数据并点击计算，即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg，平均每只动物的体重为20 g，每只动物的给药体积是100 μL，动物数量为20只，则该动物实验的总需药量为4 mg，工作液终浓度为2 mg/mL。
1：鉴于实验过程的损耗，建议您至少多配1-2只动物的量；
2：为该产品最终给药时的浓度。
