Biological activity was determined by its inhibitory effect of IL - 8 production in human PBMC by human sTRAIL/Apo2L. 95 % inhibition (100 ng/mL of s TRAIL/Apo2L) was reached using a concentration of 100 ng/mL of sTRAIL Receptor - 1.
Pureté
< 98 % by SDS-PAGE gel and HPLC analyses.
niveau d'endotoxine
Endotoxin level is less than 0.1 ng per μg (1 EU/μg).
As with any protein, exposing Soluble TRAIL Receptor-1 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
Stock
-20 °C
Stockage commentaire
The recombinant protein is stable for at least 2 years from date of receipt at -20 °C. Reconstituted Soluble TRAIL Receptor-1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20 °C.

Sujet
TRAIL Receptor-1/DR4 and TRAIL Receptor-2/DR5 belong to the TNFR superfamily of transmembrane proteins and contain a cytoplasmic "death domain, " which can activate the cell's apoptotic machinery. These receptors are activated by binding to either membrane anchored or soluble TRAIL/Apo2L. Recombinant human soluble TRAIL Receptor-1/DR4 is a 22.7 kDa protein (215 amino acid residues) consisting of the TNFR homologous, cysteine rich portion of the extracellular domain.
