应用

该重组变异建议用于:吸收、分散、代谢和排泄(ADME)药理学研究;细胞培养;药物递送研究;细胞冻存。

生化/生理作用

白蛋白是可见于动物体液和组织及部分植物种子的一类可溶性单体蛋白。 血清白蛋白可作为类固醇、脂肪酸和甲状腺激素的载体蛋白。 血清白蛋白在调节血液的胶体渗透压方面也至关重要。

物理属性

Asp N末端缺失的重组构建体。X射线晶体学证实了其与天然白蛋白的结构等同性。Asp N末端是主要的Cu2+和Ni2+ 螯合位点;其缺失消除了一个重要的抗原决定簇,让蛋白质具有低过敏源性。还可在Cys34处阻断,改善稳定性、单体含量和均质性。

外形

磷酸盐缓冲盐水溶液,含有4 mM辛酸钠和 4 mM N-乙酰色氨酸。

  5. What is the molecular mass of the recombinant albumin used in preparing Product A7223, Albumin human - recombinant?

    1 answer
    1. This recombinant protein contains 584 amino acid residues (66,357 Dalton) derived from the prototypical human serum albumin sequence, Gene Bank Accession No. M12523, with a single deletion of the N-terminal residue (Asp).  The N-terminal deletion of the Asp reduces the affinity by which nickel and copper bind to the protein.  Otherwise, the biological properties are identical as for the full-length protein.
