IL 13 Protein

• Catalog Number: orb429402
• Category: Proteins
• Description: Recombinant of IL 13 protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Purity: Greater than 95% as determined by SDS-PAGE.
• Solubility (25°C): It is recommended to reconstitute the lyophilized Interleukin 13 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Source: Escherichia Coli
• Biological Activity: ED50 range = 2-6 ng/mL as determined by the dose dependent proliferation of human TF-1 cells. Optimal concentration for individual application should be determined by a dose response assay.
• Storage: Stability: Lyophilized Interleukin-13 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL13 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
• Buffer/Preservatives: The protein (1mg/ml) was lyophilized with no additives.
• Alternative names: NC300, ALRH, BHR1, P600, IL-13.
• Note: For research use only
• Application notes: Protein content: Protein quantitation was carried out by two independent methods:1. UV spectroscopy at 280 nm using the absorbency value of 0.69 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a calibrated solution of IL-13 as a Reference Standard
• Expiration Date: 6 months from date of receipt.
