General description

Immunoglobulin G (IgG) is part of the family of glycoprotein immunoglobulins which stage immune responses against pathogenic organisms. IgG contributes to the immune response by mobilizing innate immune effector cells and inducing and pro-inflammatory responses. Such proinflammatory responses are mediated by Fcg receptors which interact with sialylated Fc fragments on IgG molecules.


This antibody demonstrates minimal to no cross reactivity against Mouse IgG, Rabbit IgG, Rat IgG, Hamster IgG, Guinea Pig IgG, and Chicken IgY.

This antibody demonstrates specificity with Human IgG (IgG>IgM>IgG Fc>IgG Fab>IgA>IgM Fc).


Purified human IgG


ELISA Analysis: As little as 0.025 µg/mL of this antibody detected Human IgG (IgG>IgM>IgG Fc>IgG Fab>IgA>IgM Fc).
