Human 4-1BB Receptor

Synonyms :

TNFRSF9, CD137 antigen, T-cell antigen ILA

Description :

4-1BB Receptor, a member of the TNF superfamily of receptors, is mainly expressed on the surface of a variety of T cells, but also found in B cells, monocytes, and various transformed cell lines. 4-1BB Receptor binds to 4-1BBL to provide a co-stimulatory signal for T lymphocytes. Signaling by 4-1BB Receptor has been implicated in the antigen-presentation process and generation of cytotoxic T cells. The human 4-1BB Receptor gene codes for a 255 amino acid type I transmembrane protein containing a 17 amino acid N-terminal signal sequence, a 169 amino acid extracellular domain, a 27 amino acid transmembrane domain and a 42 amino acid cytoplasmic domain. Recombinant human soluble 4-1BB Receptor is a 167 amino acid polypeptide (17.7 kDa), which contains the cysteine rich TNFR-like extracellular domain of 4-1BB Receptor.

E.coli

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted 4-1BBR is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per µg (1EU/µg).

Biological Activity :

Determined by its inhibitory effect of the 4-1BBL mediated stimulation of IL-8 production by human PBMC. About 90% of inibition was seen using a concentration of 1µg for both 4-1BBL and 4-1BBR.
