IgG3 Fc, IGHG3
Recombinant Human IgG3-Fc / IGHG3 Region (Human IgG3-Fc / IGHG3 Region) Glu 99 - Lys 377 (Accession # P01860) was produced in human 293 cells (HEK293) at ACROBiosystems.
Human IgG3-Fc / IGHG3 Region has a calculated MW of 31.2 kDa. The predicted N-terminus is Glu 99. The reducing (R) protein migrates as 40-50 kDa in SDS-PAGE due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH7.5. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for reconstitution instructions and specific concentrations.
Avoid repeated freeze-thaw cycles.
No activity loss was observed after storage at:
In lyophilized state for 1 year (4oC); After reconstitution under sterile conditions for 3 months (-70oC).
Human IgG3 Fc, Tag Free on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Immunoglobulin G3 (IgG3) is a member of many immunoglobulin G developed and secreted by effective B cells. In wake of cutting by pepsin, IgG is divided into two F(ab)s with one antigen binding site and a high conserved Fc segment. The Fc segment bears a highly conserved N-glycosylation site. Ig gamma-3 chain C region (IgG3-Fc / IGHG3) contains two constant regions of IgG3 H chain (CH2, CH3).
