Purity:
Greater than 98.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized Interleukin-1b in sterile 18MΩ–cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
Mouse IL-1b was lyophilized from a 0.2 µm filtered concentrated (1.0mg/ml) solution in PBS, pH 7.5.
Stability:
Lyophilized Interleukin-1b although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution IL1b 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 ED50 as determined by the dose-dependant stimulation of mouse D10S cells was found to be less than 2.0 pg/ml, corresponding to a Specific Activity of 5.0 x 108 IU/mg.
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.
