IgG H Chain


Human IgG4 H Chain C Region (Full Length), Tag Free (IG4-H5218) is expressed from human 293 cells (HEK293). It contains AA Ala 1 - Lys 327 (Accession # P01861).

Predicted N-terminus: Ala 1

Molecular Characterization

IgG H Chain(Ala 1 - Lys 327)P01861

This protein carries no "tag".

The protein has a calculated MW of 35.9 kDa. The protein migrates as 35 kDa and 43-44 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.


Less than 1.0 EU per μg by the LAL method.


>90% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Ig gamma-4 chain C region (IGHG4) is also known as IgG4 H Chain C Region, is a member of many immunoglobulin G developed and secreted by effective B cells. IgG4 is an antibody moleculer induced by infection. Immunoglobulins are composed of four peptides chain-two heavy gamma chains and two light chains. Ig gamma-4 chain C region / IGHG4 contains three constant regions of IgG4 H chain (CH1, CH2, CH3) and with a 12 aa hinge region between CH1 and CH2.
