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.
Functional grade preclinical antibodies are manufactured in an animal free facility using only in vitro protein free 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.
Storage and Handling
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.
Country of Origin
Next Day 2-8°C

Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
Clone OX-86 reacts with murine CD134 (OX-40, TNFSF4).
CD134 is expressed on activated CD4 and CD8 T cells, activated regulatory T cells, B cells, NKT cells, NK cells, and neutrophils.
CD134 functions as an important immune checkpoint, and its depletion in murine mouse models demonstrate that lack of CD134 expression leads to reduced CD4+ and CD8+ T cells1. When CD134 is bound by its corresponding ligand (OX-40L), an optimal T cell response is generated and plays a significant role in determining the amount of memory T-cells remaining after the immune response1. CD134 has also been found to play an important role in carcinogenesis, as treatment with activating in vivo antibodies against CD134 enhanced tumor growth, suggesting that CD134 is an important tumor suppressor, and its absence disrupts the immune response to tumors2,3.
