描述

Streptomyces Avidinii The streptavidin protein, although its exact biological function is unknown, forms a strong non-covalent complex with biotin, binding one molecule to each subunit. Its specific affinity for biotin suggests its application in processes requiring specific binding to biotinylated molecules. Streptomyces Avidinii Streptavidin Protein is the recombinant Streptomyces Avidinii Streptavidin protein, expressed by E. coli , with tag free. The total length of Streptomyces Avidinii Streptavidin Protein is 128 a.a., with molecular weight of ~14.3 kDa.

研究背景

阿维丁链霉菌链霉亲和素蛋白虽然其精确的生物学功能仍然难以捉摸,但表现出与生物素形成牢固的非共价特异性复合物的独特能力,其中链霉亲和素的每个亚基包含一个生物素分子。这种相互作用凸显了该蛋白质对生物素的特殊亲和力,表明其在需要与生物素化分子特异性结合的各种分子和细胞过程中的潜在应用。在结构上,链霉亲和素形成同源四聚体,进一步强调了其四级排列和该寡聚构型中的潜在功能相关性。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
