(GMP-TL506) Recombinant Human IL-7 Protein, 100μg
Beschreibung
Product Information
Protein sequence: A DNA sequence encoding the human IL-7（P13232-1：D26-H177）was expressed with a Fc-tag at the C-terminus.
Expression Host: CHO cells
QC Testing Purity: > 95 % as determined by SDS-PAGE and HPLC.
Activity: A cell proliferation assay was performed with PHA-activated PBMC cells with a corresponding specific activity of >1×107 IU/mg (calibrated according to the human IL-7 reference standard (NIBSC code: 90/530).
Endotoxin: < 0.01 EU per 1μg of the protein as determined by the LAL method.
Molecular Mass: The recombinant human IL-7 protein predicts a molecular mass of 43.8 kD.
Formulation: Lyophilized from sterile PBS, pH 7.4. Normally 6 % mannitol are added as protectants before lyophilization.
Stability & Storage: Lyophilized preparation can be stored at -20 ℃. 6 months at -20℃ under sterile conditions after reconstitution. 12 months at -80℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities after reconstituting with water for injection, normal saline or PBS, and keep the diluted concentration above 100μg/mL. Avoid repeated freeze-thaw cycles.
