Recombinant Human TNF-Related Apoptosis-Inducing Ligand (TNFSF10)
|Description||A cytotoxic protein, TRAIL initiates apoptosis in tumor cells by binding the death-signalling receptors; DR4 and DR5. In its active conformation, TRAIL forms homotrimers. TRAIL transcripts have been shown to be constitutively expressed in a variety of human tissues. There are five known TRAIL receptors: two which transduce apoptotic signals, two which function as decoys to block TRAIL-induced apoptosis and osteoptotegrin.|
|Molecular Weight||19.5 kDa|
|Endotoxin Level||< 1.0 EU/μg of recombinant protein as determined by the LAL method.|
|Purity||>95% as determined by SDS-PAGE|
|Formulation||Lyophilized from a 0.2 μm filtered solution in PBS with BSA as a carrier protein.|
|Reconstitution||Reconstitute at 20 μg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin|
|Storage||The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.|
|Usage||For research use only. Not for diagnostic or therapeutic use.|
· Endotoxin is generally measured in Endotoxin Units per milliliter (EU/mL).
· For recombinant proteins: EU is reported per microgram of protein.
· One EU = 0.1-0.2 ng endotoxin/µg of protein.
· At abm, we do the LAL chromogenic assays that can detect down to 0.01 EU/ml.
