Anti-Human TCR Vα24-Jα18 (iNKT cell)- Purified in vivo PLATINUM™ Functional Grade

Mouse IgG1 PLATINUM, Clone hksp OR Mouse IgG1 PLATINUM, Clone hksp84

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.

Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Leinco’s Purified Functional PLATINUM^TM antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.

Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Clone 6B11 recognizes the invariant CDR3 region of the human Vα24-Jα18 TCR.

TCR Vα24-Jα18 antibody, 6B11, recognizes the CDR3 region of the V alpha 24 and J alpha 18 TCR alpha locus (Vα24-Jα18). The Vα24-Jα18 semi-invariant TCR is expressed on a highly conserved T cell subset, named invariant natural killer T (iNKT cells), which also express NK cell-associated molecules. The Vα24-Jα18 TCR recognizes lipid antigens, such as α-galactosylceramide (α-GalCer), presented by the MHC class I-like molecule CD1d¹. Following activation, iNKT cells rapidly proliferate and produce large amounts of IL-4, IFNγ, and cytolytic mediators^2,3. iNKT cells have both inflammatory and immunoregulatory functions and are implicated in anti-tumor immunity, protection against infections, suppression of autoimmunity, and the development of inflammatory diseases^4.

The Vα24-Jα18 TCR is expressed on iNKT cells.
