IL-12 p40 Rat mAb - Primary antibody, specific to IL-12 p40, Rat IgG2a

Cat. No.: Ab109858
AVAILABLE TO ORDER
GRADE & PURITY Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Validated ? Validated grade — performance confirmed in defined applications before release. Use when you want documented assurance the reagent works as stated. Azide Free ? Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory. PBS Only ? PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers. ≥95%(SDS-PAGE) See COA

Overview

Rat anti Mouse IL-12 p40 Antibody, Monoclonal (C17.8), could be used for in vivo IL-12p40 neutralization, p40 affinity chromatography, IP, ELISA, Flow, WB and so on.
Application:
in vivo IL-12p40 neutralization: Use at an assay dependent concentration. 
p40 affinity chromatography: Use at an assay dependent concentration.
IP: Use at an assay dependent concentration. 
ELISA: Use at an assay dependent concentration. 
Flow: Use at an assay dependent concentration. 
WB: Use at an assay dependent concentration.
Protein Function
Cytokine that can act as a growth factor for activated T and NK cells, enhance the lytic activity of NK/lymphokine-activated killer cells, and stimulate the production of IFN-gamma by resting PBMC.
Associates with IL23A to form the IL-23 interleukin, an heterodimeric cytokine which functions in innate and adaptive immunity. IL-23 may constitute with IL-17 an acute response to infection in peripheral tissues. IL-23 binds to an heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes production of proinflammatory cytokines. IL-23 induces autoimmune inflammation and thus may be responsible for autoimmune inflammatory diseases and may be important for tumorigenesis.
