Anti-Human CD119 In Vivo Antibody – Low Endotoxin (GIR 208) [ICH1028]

ichorbio’s anti-CD119 In Vivo Antibody – Low Endotoxin (GIR 208) is manufactured in a cGMP compliant facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.

Anti-CD119 In Vivo Antibody – Low Endotoxin (GIR 208) recognizes Human IFN gamma R alpha

This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

The IFN-gamma receptor is expressed at moderate levels on virtually every cell with the exception of erythrocytes.

Interferon-gamma (IFN-gamma) exerts its biologic effects by interacting with a single high affinity receptor, IFN-gamma receptor. This receptor is present on almost all cell types except mature erythrocytes. The IFN-gamma receptor consists of two polypeptide chains alpha and beta and requires association of JAK1, JAK2 and Stat1 for IFN-gamma signal transduction. In signal transduction, IFN-gamma induces tyrosine phosphorylation of IFN-gamma receptor alpha (IFNGR1) leading to the formation of a docking site on the activated receptor for Stat1, which specifically activates IFN-gamma induced gene transcription. The IFN-gamma receptor is structurally related to the recently cloned IL-10 receptor. GIR 208 binds IFNGR1 and blocks binding of IFN-gamma to the receptor.
