产品背景

Antibodies, also known as immunoglobulins (Igs) are critical for immunity and are grouped into five primary classes: IgG, IgM, IgA, IgD, and IgE. The most abundant antibody isotype is immunoglobulin G (IgG) with concentrations ranging from 7.5-22 mg/ml in human serum and has a molecular weight of 150 kDa. The major effector functions of IgG include neutralization, opsonization, complement fixation and antibody dependent cell-mediated cytotoxicity (ADCC). This monomeric immunoglobulin, expressed on the surface of mature B cells, is often depicted as a Y-shape and comprised of 2 heavy chains and 2 light chains linked by disulfide bonds. The heavy chain is type gamma including subtypes gamma 1, gamma 2, gamma 3, and gamma 4 while the light chain is either a kappa or lambda chain. An IgG molecule has two antigen binding sites, each consisting of a heavy and light chain N-terminal variable domain. When combined with the constant heavy chain 1 (Ch1) and the constant light chain domains, it forms the fragment antigen-binding (Fab) region (2 per antibody). The remaining domains (Ch2-Ch4) of both heavy chains make up the Fc region and contain a site for covalently linking an enzymatic or fluorochrome probe, such as HRP or Janelia Fluor 549, for target detection and visualization.

The 4 IgG subclasses, sharing 95% amino acid identity, include IgG1, IgG2, IgG3, and IgG4 for humans and IgG1, IgG2a, IgG2b, and IgG3 for mice. The relative abundance of each human subclass is 60% for IgG1, 32% for IgG2, 4% for IgG3, and 4% for IgG4. In an IgG deficiency, there may be a shortage of one or more subclasses.

本辣根过氧化物酶标记山羊抗小鼠IgG(H+L)(HRP-labeled Goat Anti-Mouse IgG(H+L))，用于Western、ELISA和IHC等的二抗。HRP，即horseradish peroxidase，中文名为辣根过氧化物酶，可以在Western检测时催化ECL类试剂(如ECL、BeyoECL等)产生化学发光，可以在ELISA时催化TMB产生蓝色，也可以在IHC或Western blot检测时催化DAB产生棕色沉淀。
 

本辣根过氧化物酶标记山羊抗小鼠IgG(H+L)用于WB、ELISA和IHC的推荐稀释比例参考上表，实际实验操作过程中需根据抗原和抗体的具体情况适当调节二抗的稀释比例。
对于WB，推荐的稀释范围为1:500-2000。
 

本抗体为用纯化的小鼠IgG免疫山羊，然后用亲和纯化柱对获得的抗血清进行纯化，并经过人IgG吸附纯化的优质二抗。对人IgG几乎没有结合能力。
 

本抗体如果用于常规的Western检测，以每次检测需10毫升1:1000稀释的二抗计，至少可以检测100次。
