描述:
The 4S.B3 monoclonal antibody specifically binds to interferon-γ
(IFN-γ). The immunogen used to generate this hybridoma was partially
purified human IFN-γ
obtained from supernatants of human PBMC stimulated with
Staphylococcus aureus. Interferon-γ(IFN-γ) is a potent
multifunctional cytokine that is produced by several activated cell types including NK, NKT, CD4+TCR
αβ+, CD8+TCRαβ+, and TCRγδ+ Tcells. IFN-γexerts its biological effects through specific binding to the high-affinity IFN-γReceptor Complex comprised of IFN-γRα(CD119)and IFN-γRβ
subunits. In addition to its antiviral effects, IFN-γ
upregulates a number of lymphoid cell functions including the antimicrobial
and antitumor responses of macrophages, NK cells, and neutrophils. In addition, IFN-
γ
can exert strong regulatory influences on the
proliferation, differentiation, and effector responses of B cell and T cell subsets. These influences can involve IFN-γ’s capacity to boost MHC
class I and II expression by antigen-presenting cells as well as to direct effects on B cells and T cells themselves. Human IFN-γis a 14-18 kDa
glycoprotein containing 143 amino acid residues.
The antibody was conjugated to BD Horizon™ BV786 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. This dye is a
tandem fluorochrome of BD Horizon™ BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 786-nm. BD Horizon™
BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
