Measure by its ability to induce IL-2 secretion in mouse T cells in the presence of the anti-CD3 antibody.
The ED50 for this effect is <25 ng/mL.

OX40L, a member of the TNF superfamily of structurally related proteins, exists primarily as a type II membrane bound, non-covalently linked homotrimeric protein. The OX40L is stably expressed on many antigen-presenting cells, such as activated B cells, mature dendritic cells, Langerhans cells, and macrophages. Interactions between OX40 and OX40L can regulate the division and survival of T cells. Its inhibition effect can make the effector T cells conversing into regulatory T cells (Tregs) and promote the recall response in memory T cells.

The protein was lyophilized from a solution containing 1X PBS, pH 7.4.

It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 100 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

Blue Ice

Lyophilized protein should be stored at -20°C for 1 year.
Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1%
BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months.
