Product Description: | Recombinant Human Tumor Necrosis Factor Beta is produced by our E.coli expression system and the target gene encoding Leu35-Leu205 is expressed. |
UniProt ID: | P01374 |
Species: | Human |
Expression System: | E.coli |
Tag: | Tag free |
Predicted MW: | 18.8 KDa |
SDS-PAGE: | 15 KDa, reducing conditions |
Formulation: | Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. |
Endotoxin Level: | Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test. |
Activity: | Measured in a cytotoxicity assay using L‑929 mouse fibroblast cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is 20-80 pg/ml. |
Purity: | >95% |
Reconstitution: | Always centrifuge tubes before opening.Do not mix by vortex or pipetting. |
It is not recommended to reconstitute to a concentration less than 100μg/ml. | |
Dissolve the lyophilized protein in distilled water. | |
Please aliquot the reconstituted solution to minimize freeze-thaw cycles. | |
Stability and Storage: | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. |
Reconstituted protein solution can be stored at 4-7°C for 2-7 days. | |
Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
