Purity:
Greater than 95% as obsereved by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized TNF-a in sterile water not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The TNF-a protein was lyophilized from 1mg/ml in 1xPBS.
Stability:
Lyophilized TNF-a although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution TNF-a should be stored at 4 °C between 2-7 days and for future use below -18 °C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Activity:
The specific activity was determined by the dose-dependent cytotoxity of the TNF alpha sensitive cell line L-929 in the presence of Actinomycin D and is typically 0.05-0.5ng/ml.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
