Application:

WB IHC

Reactivity:

Human

Dilution:

WB 1:1000~1:2000 IHC 1:500~1:1000

	Western blot analysis of IgG4 expression in Human spleen lysate.
	Immunohistochemical analysis of paraffin-embedded human stomach carcinoma, using IgG4 Antibody .

Purification:

Affinity-chromatography

Specificity:

IgG4 Antibody detects endogenous levels of total IgG4

Immunogen:

A synthesized peptide derived from human IgG4

Description:

IgG4 antibodies will dominate the IgG response in schistosomiasis, lymphatic filariasis, and in patients after allergen immunotherapy. Unlike the other IgG subclasses, IgG4 does not activate complement. A combined IgA-IgG4 deficiency has been associated with recurrent pyogenic infections.

Rabbit IgG in phosphate buffered saline , pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol. Store at +4°C short term. Store at -20°C long term. Avoid freeze / thaw cycle.
