Active Recombinant Mouse lgfbp4 protein, His-tagged

• Cat.No.: lgfbp4-760M
• Product Overview: Recombinant Mouse lgfbp4 protein(NP_034647.1)(Met1-Glu254), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Mouse
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured in a serum free cell proliferation assay using MCF7 human breast adenocarcinoma cells (Karey, K.P. et al. 1988, Cancer Research 48: 4083.). The ED50 for this effect is typically 0.1-0.6 μg/ml.
• Molecular Mass: The secreted recombinant mouse IGFBP4 consists of 244 amino acids and has a calculated molecular mass of 27.2 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 38 kDa protein in SDS-PAGE under reducing conditions.
• Protein Length: Met1-Glu254
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
