Product name Human Receptor II for the Fc region of immunoglobulin G (FcGRII) ELISA Kit
Reactivity Human
Applications ELISA
Applications notes This Human Receptor II for the Fc region of immunoglobulin G (FcGRII) ELISA Kit employs a two-site sandwich ELISA to quantitate FcGRII in samples. An antibody specific for FcGRII has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyFcGRII present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for FcGRII is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of FcGRII bound in the initial step. The color development is stopped and the intensity of the color is measured.
Detection method Colorimetric
SampleType Cell culture supernatants, Other biological fluids, Plasma, Serum
Assay type Sandwich ELISA (quantitative)
Assay duration Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.
Alternative FcGRII; CD32; FCGR2A; FCG2; FCGR2A1; FCGR2; FCGR2B; FCGR2C; Fc Fragment Of IgG, Low Affinitya, Receptor

Usage notes • Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
Storage instructions The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping Gel pack with blue ice.

Additional Information

Background CD32 is a surface receptor protein and part of a large population of B cell co-receptors. It has a low-affinity for IgG antibodies and down-regulates antibody production in the presence of IgG. This feedback loops essentially lowers the production of IgG produced by B cells when there is a surplus in the body.Monoclonal antibodies can distinguish between type A and type B.Receptors for the Fc portion of IgG such as FCGR2A play an essential role in the protection of the organism against foreign antigens by removing antigen-antibody complexes from the circulation. Receptors are present on monocytes, macrophages, neutrophils, natural killer (NK) cells, and T and B lymphocytes, and they participate in diverse functions such as phagocytosis of immune complexes and modulation of antibody production by B cells.
