Recombinant Mouse TNF
简单描述
The MP6-XT22 antibody specifically binds to mouse Tumor Necrosis Factor (TNF, also known as TNF-α). TNF is produced by many activated cell types including monocytes, macrophages, astrocytes, granulocytes, mast cells, T and B lymphocytes, NK cells, keratinocytes, fibroblasts, adipocytes, and certain tumor cells. Activated cells express type II transmembrane TNF glycoproteins that associate as homotrimeric complexes. After enzymatic cleavage, the extracellular regions of membrane TNF are shed as soluble homotrimers. TNF is a potent multifunctional cytokine that can exert regulatory and cytotoxic effects on a wide range of normal lymphoid and non-lymphoid cells and tumor cells. Although TNF serves as a primary mediator in protective immune responses against microbial and viral pathogens, it can also drive systemic pathophysiologic responses including septic shock, cachexia and autoimmune diseases. Mouse TNF exerts its biological activities by binding and signaling through cell surface membrane Type I and Type II TNF Receptors (aka, TNFRI/CD120a and TNFRII/CD120b, respectively).

产品详情
PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.

Expression of TNF by MiCK-1 cells. MiCK-1 cells (Cat. No. 554652) were stained with 0.06 ug of FITC-conjugated rat anti-mouse CD4 (FITC-RM4-5, Cat. No. 553047), fixed, permeabilized, and subsequently stained with 0.06 ug of PE-conjugated rat anti-mouse TNF antibody (PE-MP6-XT22, Cat. No. 554419) by using the Pharmingen staining protocol (left panel). To demonstrate specificity of staining, the binding of PE-MP6-XT22 was blocked by the preincubation of the conjugated antibody with molar excess of recombinant mouse TNF (0.25 µg, Cat. No. 554589; right panel), and by preincubation of the fixed/permeabilized cells with an excess of the unlabelled MP6-XT22 mAb (2 µg, Cat. No. 554416; data not shown). The quadrant markers for the bivariate dot plots were set based on the autofluorescence control, and verified with the recombinant cytokine blocking (right panel) and unlabelled antibody blocking specificity controls.
