Porcine IL4 Protein

• Catalog Number: orb611015
• Category: Proteins
• Description: Recombinant Porcine IL4 protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: The protein was lyophilized from a sterile (0.2µm) filtered solution containing 10 mM sodium phosphate, pH 7.5.
• Purity: Greater than 95.0% as determined by SDS-PAGE.
• Protein Sequence: MHKCDITLQE IIKTLNILTA RKNSCMELPV TDVFAAPENT TEKETFCRAS TVLRHIYRHH TCMKSLLSGL DRNLSSMANM TCSVHEAKKS TLKDFLERLK TIMKEKYSKC
• Application notes: Cytokines And Growth Factors
• Source: Escherichia Coli
• Biological Activity: The ED50, as determined by TF-1 cell proliferation is 0.504ng/ml corresponding to a specific activity which is 2.0 x 10^6 units/mg.
• Solubility (25°C): It is recommended to reconstitute the lyophilized IL-4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Storage: Stability: Lyophilized IL-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-4 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles
• Alternative names: BCGF, BCDF, B cell stimulating factor, BSF-1, Lymp
