Overview

Catalog No.	HB651226
Species reactivity	Human
Applications	ELISA, Bioactivity: FACS, Functional assay, Research in vivo
Host species	Human
Isotype	IgG
Clone ID	JMW-3B3
Biological activity	Biotinylated JMW-3B3 (10 ug/mL) specifically detects sCTLA-4 in PBMC cell culture supernatants, and reveals no population-level difference in sCTLA-4 production between SLE patient and healthy donor PBMC stimulated with lupus-associated autoantigenic peptides [1]. JMW-3B3 (10 ug/mL; 5 days) blocks sCTLA-4 activity in PBMC from both healthy donors and SLE patients, with effects that vary by stimulant: it suppresses some pro-inflammatory and proliferative responses in healthy donors, while enhancing IL-10 production (and altering proliferation/cytokine profiles) in SLE patient PBMC, accentuating the inherent cytokine response differences between the two groups [1]. JMW-3B3 (20 ug/mL; overnight at 4°C) selectively binds intracellular sCTLA-4 in G-361 human malignant melanoma epithelial cells, but does not detect sCTLA-4 in A-375 human malignant melanoma epithelial cells [2]. JMW-3B3 (10 ug/mL; 5 days) enhances IFN-γ production from melanoma patient PBMC stimulated with a low dose (0.02 ug/mL) of anti-CD3 mAb for 5 days, relative to ipilimumab treatment [2]. JMW-3B3 (10 ug/mL; 5 days) enhances IL-17A production from healthy donor PBMC stimulated with a high dose (1 ug/mL) of anti-CD3 mAb for 5 days, relative to ipilimumab treatment [2].

Background	Cytotoxic T-lymphocyte protein 4 (CD152/CTLA4) is a ~24 kDa protein. Inhibitory receptor acting as a major negative regulator of T-cell responses. Acts as a decoy receptor: the affinity of CTLA4 for its natural B7 family ligands, CD80 and CD86, is considerably stronger than the affinity of their cognate stimulatory coreceptor CD28. CD152 is the therapeutic target of ipilimumab (Yervoy). 1. Schwartz, JC. et al. (2001) Nature 410, 604-8. PMID: 11279501 2. Stamper, CC. et al. (2001) Nature 410, 608-11. PMID: 11279502 3.
