Target Name: Human Interleukin-2; IL-2; T-Cell Growth Factor; TCGF; Aldesleukin; IL2

Source: Recombinant Human IL-2 (accession number P60568) (Ala21-Thr153) is expressed by the E.coli expression system.

Molecular Weight: The 133 amino acid protein has a predicted molecular weight of 15.5 kDa. The protein migrates at approximately 14 kDa on SDS-PAGE with DTT-reduced condition

Purity: >95% based on SDS-PAGE

Formulation: Lyophilized from a 0.2 μm filtered solution of 10mM sodium citrate, pH 4.0.

Vial Size: 10µg, 50µg

Endotoxin Level: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Storage and Handling: 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.
