Recombinant Human 4-1BB/TNFRSF9 Protein(HEK293) , His

4-1BB/TNFRSF9

4-1BB (CD137; TNFRSF9), a receptor of TNFSF9/4-1BBL, belongs to the tumor necrosis factor (TNF) receptor superfamily[1]. 4-1BB is helpful for T cell activation and development, and also induces peripheral mononuclear cell proliferation and migration to the tumor microenvironment[2]. 4-1BB is also involved in enhancing Nrf2 and NF-κB pathway mediated apoptosis of endothelial cells[3]. Human 4-1BB protein is a surface glycoprotein with a transmembrane domain (187-213 a.a.). 4-1BB/TNFRSF9 Protein, Human (HEK293, His) is the extracellular part (L24-Q186) of 4-1BB protein, produced by HEK293 cells with C-terminal 6*His-tag.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
