Recombinant Cynomolgus Monkey IgG1 Fc protein

Cat.No.: IgG1 Fc-228C
Product Overview: Recombinant Cynomolgus Monkey IgG1 Fc(Pro110-Lys333) was expressed in HEK293.
Description: Immunoglobulin G (IgG), is one of the most abundant proteins in serum with normal levels between 8-17 mg/mL in human adult blood. It is composed of two heavy chains and two light chains. The variability of the IgG pool is generated by somatic recombination in B cells that have been exposed to foreign material. IgA, IgG, IgM, IgD, and IgD classes of human immunoglobulin (as well as the isotypes IgG1, IgG2a, IgG2b, and IgG3) are generated by class switch recombination within the heavy chain locus. Recombination within the light chain locus selects either kappa or lambda chains. Antibodies are secreted by plasma cells of the B lymphocyte lineage and constitute the humoral component of adaptive immunity. Their variable regions bind to foreign antigens, while their Fc regions are recognized by Fc receptors expressed on macrophages, monocytes, neutrophils, NK cells, and CD8+ cytotoxic T cells. Phagocyte uptake of antibody-antigen complexes and antibody-opsonized pathogens is critical for clearance of the foreign material and immune homeostasis.
Source: HEK293
Species: Cynomolgus Monkey
Predicted N Terminal: Pro110, and Ala-Leu-Ala-Pro110
Form: Lyophilized from a 0.2 μm filtered solution in PBS.
Bio-activity: Measured by its binding ability in a functional ELISA. When Recombinant Cynomolgus Monkey IgG1 Fc is immobilized at 0.15 µg/mL (100 µL/well), the concentration of Recombinant Human Fc gamma RI/CD64 that produces 50% of the optimal binding response is 0.2-1.2 ng/mL.
