Porcine IL 2 Bioactive Protein Product Attributes
Product Type: Bioactive Protein
Recombinant IL 2 based upon sequence from Porcine
Host: QP10699 protein expressed in E. Coli.
Available Tags: Untagged
Protein Construction: A cDNA sequence encoding the sequence of IL 2 was constructred and used to recombinantly synthesize the protein.
Recommended Applications: Bioactive
Recommended Reconstitution Instructions: It is recommended to reconstitute the lyophilized IL 2 in sterile distilled H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Bioactivity Data: The ED50 as determined by a cell proliferation assay using murine CTLL-2 cells is less than 0.5ng/ml, corresponding to a specific activity of > 2.0 Ã 106 IU/mg.

Purity: Greater than 96.0% as determined by:(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Buffer: The protein (1 mg/ml) was lyophilized was lyophilized from a 0.2µm filtered concentrated solution in 1ÃPBS, pH 7.4.
Storage Conditions: Lyophilized IL2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-2 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.
Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
