Short Description: Recombinant Mouse OX40 Ligand is produced by our Mammalian expression system and the target gene encoding Ser51-Leu198 is expressed with a 8His tag at the N-terminus.

Shipping: Ambient

Formulation: Lyophilized from a 0.2 m filtered solution of PBS, pH7.4.

Storage: Lyophilized protein should be stored at < -20C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20C for 3 months.

Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 g /ml.
Dissolve the lyophilized protein in ddH2O.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Purity: Greater than 95% as determined by reducing SDS-PAGE.

Endotoxin: Less than 0.1 ng/g (1 IEU/g) as determined by LAL test.

Background: OX40 ligand (OX40L) , also called CD252, is a single-pass type II membrane protein of the TNF/TNF receptor superfamily. OX40L is expressed by DCs, macrophages and B cells and signals via its cognate receptor OX40 which is mainly expressed on APCs. OX40L/OX40 interactions are important in T-cell activation and survival and for the generation of memory T cells from activated effector T cells. OX40LOX40 co-stimulation leads to activation of TNF receptor associated factor (TRAF) 2, 3 and 5. This pathway has been shown to prolong the survival of effector CD4+Th cells as well as contributes to generation of memory T cells.
