Regulatory Status Legend
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).
The antibody was conjugated to BD Horizon™ BV650 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 650-nm. BD Horizon™ BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor® 700 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
BV650 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 650 nm. Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor® 700 detectors. BV650 will have moderate spillover into the BD Horizon™ BV711 detector.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated with BD Horizon™ BV650 under optimum conditions, and unconjugated antibody and free BD Horizon™ BV650 were removed.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
