Liquid or Lyophilized powder缓冲液:
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.储存条件:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.保质期:
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.货期:
3-7 business days注意事项:
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.功能1:
Potent inhibitor of the complent mbrane attack complex (MAC) action. Acts by binding to the C8 and/or C9 complents of the assbling MAC, thereby preventing incorporation of the multiple copies of C9 required for complete formation of the osmolytic pore. This inhibitor appears to be species-specific. Involved in signal transduction for T-cell activation complexed to a protein tyrosine kinase.The soluble form from urine retains its specific complent binding activity, but exhibits greatly reduced ability to inhibit MAC assbly on cell mbranes.功能2:

文献和实验网络 十一、同种限制因子 同种限制因子(homologous restriction factor,HRF),又称C8结合蛋白(C8bp)。为Zalman等(1986)用C9-Sepharose亲和层析从人红细胞膜上分离的一个能与C8、C9结合并参与C9阶段同种限制性的膜蛋白,通过GPI锚固定于细胞膜表面。新鲜红细胞膜上的HRF分子量为65kDa
网络 九、CD59 CD59是近年(1989)才发现的一种分子量只有18~20kDa的膜性调节蛋白。由Sugita等(1988年)首先描述,曾有不同的名称,如同种限制因子20(homologous restriction factor-20),保护素(protectin)及膜反应性溶破抑制物(membrane inhibitor of reactive
蛋白中,如碱性磷酸酶、乙酰胆碱酯酶、Thy-1及布氏锥虫的变异体表面糖蛋白等。补体蛋白DAF、MCP、CD59和C8bp(HRF)可借助于这样的结构而使补体对自身细胞的损伤减至最小。这就是近日逐渐阐明的补体同源限制性(homologous restriction)。阵发性血红蛋白尿(PNH)之所以对补体攻击敏感,正是由于其红细胞膜上缺乏含有GPI锚的分子,因而使机体的正常同源限制性作用失去效能所致。
