NALE„¢ Purified Human IgG4 Isotype Control Recombinant Antibody (Clone: QA16A15)

IgG4 is the least abundant immunoglobulin present in the human serum. IgG4 is implicated in a unique process called fab-arm exchange (FAE) and limits the formation of immune complex. It has anti-inflammatory properties. IgG4 functions as a therapeutic antibody. It provides protection against allergy, prevents mast cell degranulation and has a harmful role in malignant melanoma. IgG4 may be associated with autoimmune diseases such as, autoimmune pancreatitis (AIP) type 1 and 2, Mikulicz syndrome, Kuttner€2s tumor, Riedel€2s thyroiditis and tubulointerstitial nephritis.
