Active Recombinant Mouse IL4 protein

• Cat.No.: IL4-958M
• Product Overview: Recombinant Mouse IL4 protein(NP_067258.1)(His23-Ser140) was expressed in E. coli.

Specification

• Source: E. coli
• Species: Mouse
• Tag: N/A
• Form: Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured in a cell proliferation assay using HT-2 mouse T cells.The ED50 for this effect is typically 0.4-4 ng/mL.
• Molecular Mass: he recombinant mouse IL4 consists of 119 amino acids and predicts a molecular mass of 13.4 KDa. It migrates as an approximately 14 KDa band in SDS-PAGE under reducing conditions.
• Protein Length: His23-Ser140
• Purity: > 90 % 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.
