Description

Product Class: Purified
Clone ID: RF61
Synonyms: IgG1; IgG2; IgG3; IgG4; Immunoglobulin G; Immunoglobulin gamma-1; Immunoglobulin G subclass 1; Immunoglobulin gamma-2; Immunoglobulin G subclass 2; Immunoglobulin gamma-3; Immunoglobulin G subclass 3; Immunoglobulin gamma-4; Immunoglobulin G subclass 4; 274.RA.F4; RF mAb 61; mAb 61
Amount: 50 μg
Application Codes Clone: ELISA; HA
Shipping Temperature: Wet Ice
Origin Pub PMID: 17395205
Buffer Composition: PBS with 0.02% Proclin 300.
Original Format: IgM
Storage Temperature: Store at 4⁰C for up to 3 months. For longer storage, aliquot and store at -20⁰C.
Specificity Statement: This antibody is specific for the C-terminal (Cγ3) end of the Fc region of IgG1, -2, and -3, with ~10-fold lower affinity for IgG4. This antibody's binding to IgG Fc is non-inhibitable by S. aureus protein A (SpA), which binds IgG Fc at the Cγ2–Cγ3 interface; this antibody's epitope is almost as far as physically possible from the antigen-combining site of IgG and is also remote from the functional sites responsible for FcγR or C1q binding (in Cγ2) and from the N-linked carbohydrate, also in Cγ2.
Application Notes: The binding activity of this antibody's original format (human IgM) to IgG Fc fragments was measured by ELISA, and a dissociation constant (K_d) of 6.0×10^-7 M was calculated (Burastero et al., 1988; PMID: 3264319). This antibody exhibited strong reactivity with both monoclonal and polyclonal human anti-Rh IgG antibodies bearing the Gm(a) or Gm(g) specificity in hemagglutination assays (HAs), displaying a higher affinity for Gm(g). Additionally, it demonstrated efficient binding to heat-altered autologous Gm(a-), (g-) IgG and exhibited heteroclitic specificity at the clonal level in an autologous system (Williams Jr et al., 1992; PMID: 1380541). The binding of this antibody's original format to human IgG subclasses as measured by ELISA demonstrated that its binding specificity is IgG1~IgG2~IgG3>IgG4 (Duquerroy et al., 2007; PMID: 17395205).
