    Catalog Number:
    105-06
    Source:
    Escherichia coli.
    Molecular Weight:
    Approximately 7.9kDa monomeric protein, containing 72 amino acid residues, which comprises the EGF homologous portion of the Epigen precursor.
    Quantity:
    5ug/25ug/1000μg
    Purity:
    >98% by SDS-PAGE and HPLC analyses.
    Biological Activity:
    Determined by the dose-dependent stimulation of the proliferation of murine Balb/3T3 cells. The expected ED50 for this effect is 150-300 ng/ml.
    Physical Appearance:
    Sterile Filtered White lyophilized (freeze-dried) powder.
    Formulation:
    Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in PBS, pH 7.4.
    AA Sequence:
    AVTVTPPITA QQADNIEGPI ALKFSHLCLE DHNSYCINGA CAFHHELEKA ICRCFTGYTG ERCEHLTLTS YA
    Endotoxin:
    Less than 1EU/μg of rHuEPG as determined by LAL method.
    Reconstitution:
    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
    Storage:
    This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
