Classical Complement Pathway Components C1r and C1s: Purification from Human Serum and in Recombinant Form and Functional Characterization

associates with the recognition protein C1q. The C1 complex circulates in serum as a zymogen and is activated upon binding of C1q to appropriate targets, such as antigen–antibody complexes. This property is used for the purification of C1r and C1s from human

Classical Complement Pathway Component C1q: Purification of Human C1q, Isolation of C1q Collagen-Like and Globular Head Fragments and Production of Re

The classical complement pathway (CCP) activation is a multimolecular complex, composed of three subcomponents namely C1q, C1r, and C1s. C1q is the recognition subunit of this complex and its binding to the specific targets leads

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
