Mouse IL 3 Protein

SKU: orb426513

Description

Recombinant of mouse IL 3 protein

Images & Validation

• Application Notes:
  Protein content: Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.154 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 standard solution of IL3 as a Reference Standard

Key Properties

• Source: Escherichia Coli
• Biological Activity: The ED50 as determined by the dose-dependant stimulation of murine M-NFS-60 cells is < 0.05 ng/ml, corresponding to a Specific Activity of 20,000,000IU/mg.
• Protein Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Met-Asp-Thr-His-Arg
• Purity: Greater than 97.0% as determined by:(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE.

Storage & Handling

• Storage: Stability: Lyophilized Interleukin-3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL-3 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
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: Lyophilized from a concentrated (1mg/ml) solution in water containing no additives.
• Disclaimer: For research use only
