抗-人IgG（Fc特异性）单克隆抗体

Monoclonal Anti-Human IgG (mouse IgG2a isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Immunoglobulins (Igs) belongs immunoglobulin super-family. Each immunoglobin have two heavy (H) and two light (L), held together by disulphide linkages. The light comprises of one variable N-terminal region and a constant C-terminal region. The heavy chain has one variable N-terminal region and three or four constant (CH1-CH4) C-terminal region.

Monoclonal Anti-Human IgG (Fc specific)-FITC antibody produced in mouse has been used in:

• Fluorescent Dot Immunobinding Assay (F-DIBA)
• Particle Immunofluorescent Assay (F-IFMA)
• flow cytometry

该抗体对人 IgG 的 Fc 部分具有特异性，并识别所有人 IgG 亚类共有的表位。在 IUIS/WHO 研究中，该抗体被用作 Fc 特异性试剂。

Digestion of IgG by papain results in generation of fragment antigen binding (Fab) comprising one complete L chain and a variable and CH1 region of H chain. Pepsin digestion of IgG results in fragment crystallisable (fc), containing the H chain constant region. IgG antibody have enormous therapeutic potential and the Fc is for the development of therapeutic antibody. Although the antibody site is located in the terminal end of the human IgG molecule (part of the Fab fragment), the Fc portion has various important functions such as complement fixation, site for rheumatoid factor (autoantibodies directed to Fc), passage through placental membrane and staphylococcus protein A binding.

Solution in 0.01 M phosphate buffer pH 8.0, containing 1% inactivated bovine serum albumin and 15 mM sodium azide.
