DISC: Rabbit TNF a Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant TNF a based upon sequence from Rabbit
Host: QP10882 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of TNF a was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-alpha in sterile 18Mâ¦.cm H2O not less than 100Âµg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: The ED50 as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D is less than 0.03ng/ml, corresponding to a Specific Activity of 30,000,000 IU/mg.

Purity: Greater than 95% as determined by:(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Endotoxin Levels: < 1.0 EU per ug protein as determined by the LAL method.
Buffer: TNF-alpha Rabbit was lyophilized after extensive dialysis against 20mM PBS, pH 7.4, 300mM NaCl.
Storage Conditions: Lyophilized Tumor Necrosis Factor-a although stable at room temperature for 3 weeks, should be stored desiccated below -18Â°C. Upon reconstitution TNF-a should be stored at 4Â°C between 2-7 days and for future use below -18Â°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
