蛋白名称:Human IgG2-Fc Protein (257 Ser/Ala)
蛋白构建:A DNA sequence encoding the human IgG2 Fc region (P01859) (Glu 99-Lys 327, 257Ser/Ala) was expressed and purified.
表达宿主:HEK293 Cells
蛋白纯度:> 90 % as determined by SDS-PAGE
蛋白活性:Measured by its ability to bind human CD32a-His (Cat:10374-H08H1) in a functional ELISA.
蛋白内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
预测N端:Glu 99
蛋白分子量:The recombinant human IgG2-Fc consists of 228 amino acids and has a predicted molecular mass of 25 kDa. As a result of glycosylation, the apparent molecular mass of IgG2-Fc is approximately 34 kDa in SDS-PAGE under reducing conditions.

【原创】Protein A Sepharose 之进化篇。。。
洗脱条件比较剧烈,最后收集的蛋白质很有可能变性,或者是复性困难。 这种洗脱条件剧烈的Protein A 柱结合的重组蛋白质A一般具有5个串联结构域:E、D、A、B、C。这种重组蛋白A虽然除去了不重要的非结合域,仅由5个结构域组成,每个域均可以和IgG的Fc段结合,但不同的域结合强度略有差异。因此洗脱条件不均一,而且经常需要较低的pH值。如果减少串联结构域的个数,并且采取同型结构域串联,就可以避免不同结构域与抗体Fc 段亲和性的差异,洗脱条件会温和而均一。为此,我们可以做一个试验,比较一下
Transient Production of scFv-Fc Fusion Proteins in Mammalian Cells
Single chain Fv (scFv) antibody fragments fused to the human immunoglobulin G (IgG) Fc moiety obtain IgG-like properties, but nevertheless they are still encoded by a single gene. As transient production of scFv-Fc proteins in mammalians
