• Catalog Number: orb429411
• Category: Proteins
• Description: Recombinant of primate IL4 protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: Lyophilized from a 0.2µm filtered concentrated solution in 1xPBS, pH 7.4.
• Purity: Greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
• Protein Sequence: HNCHIALREI IETLNSLTEQ KTLCTKLTIT DILAASKNTT EKETFCRAAT VLRQFYSHHE KDTRCLGATA QQFHRHKQLI RFLKRLDRNL WGLAGLNSCP VKEANQSTLE DFLERLKTIM REKYSKCSS
• Application notes: Cytokines And Growth Factors
• Source: Escherichia Coli
• Biological Activity: The ED50 as determined by the dose-dependent stimulation of TF1 cells is less than 0.2ng/ml, corresponding to a specific activity of > 5.0×106 IU/mg.
• Solubility (25°C): It is recommended to reconstitute the lyophilized Interleikin-4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Storage: Stability: Lyophilized Interleukin-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL4 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles
• Alternative names: Interleukin-4, IL-4, B-cell stimulatory factor 1,
