Immunoglobulin G Production Pathway (IgG Production Pathway)

Target
IgG Production Pathway
Molecular classification
Biological Pathway, Cellular Process
01

Overview

The immunoglobulin G (IgG) production pathway refers to the biological processes by which B cells generate IgG antibodies, as well as the industrial methods used to produce therapeutic IgG preparations from human plasma. IgG is the most abundant class of immunoglobulin in human serum and plays a central role in adaptive immunity, particularly in secondary immune responses.
