Quantification of Human IgG and Related Fc Fusion Proteins by a Human IgG/Fc Capture ELISA

of recombinant human IgGs after production and purification for further assays. Here, we describe a human IgG/Fc capture enzyme linked immunosorbent assay (ELISA) which is simple, robust, inexpensive and specific for all types of human IgGs and related Fc fusion

Fc受体 Fc receptor

　　 为对兔疫球蛋白Fc部分c末端的受体。对具有该受体的细胞，通过抗体与抗原结合时，细胞将发挥如下的特有机能：（1）原噬菌体对IgG，占多形核白细胞大部分的嗜中性细胞对IgG、IgA具有Fc受体，通常通过与抗原结合的抗体以及有时与游离的抗体（嗜细胞性抗体）结合来捕捉抗原，并经吞噬作用将之围吞。（2）B细胞的大部分（80%以上）具有对IgG的Fc受体，这些都不进行产生抗体的细胞分化，可通过与抗原抗体复合体的结合而被活化，释放产生抗体的细胞限制因子。（3）T细胞约有10%具有Fc受体，主要

Capture of the Human IgG1 Antibodies by Protein A for the Kinetic Study of h-IgG/FcR Interaction Using SPR-Based Biosensor Technology

Surface plasmon resonance (SPR) is a key technology to evaluate IgG effector functions in vitro involving binding to Fcgamma receptors (FcγR). We describe here the chemical coupling of protein A to a sensor chip. IgGs prepared
