Human IL 2 Protein

• Catalog Number: orb426482
• Category: Proteins
• Description: Recombinant of human,yeast IL 2 protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Purity: Greater than 98% as determined by SDS-PAGE.
• Solubility (25°C): It is recommended to reconstitute the lyophilized Interleukin-2 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

• Source: Pichia pastoris
• Biological Activity: The biological activity is determined by the dose dependent proliferation of mouse CTLL–2 cells. Optimal concentration for individual application should be determined by a dose response assay. ED50 range = 0.08–0.5ng/ml
• Storage: Stability: Lyophilized Interleukin-2 although stable at room temperature for 3 weeks, should be stored desiccated below -1°C. Upon reconstitution Interleukin-2 should be stored at 4C between 2-7 days and for future use below -1°C. Please prevent freeze-thaw cycles
• Buffer/Preservatives: The protein was lyophilized from a 0.2µm filtered solution in 20mM sodium phosphate buffer pH 7.0 in absence of any carrier protein.
• Alternative names: Interleukin-2, T-cell growth factor (TCGF), Interl
• Note: For research use only
• Application notes: Cytokines And Growth Factors
• Expiration Date: 6 months from date of receipt.
