(GMP-TL511) Recombinant Human IL-3 Protein, 100μg
Beschreibung
Product Information
Protein sequence: A DNA sequence encoding the human IL-3 (GenBank: AAA59146.1) was expressed with a His-tag at the C-terminus.
Expression Host: HEK293 cells
QC Testing Purity: > 90 % as determined by SDS-PAGE
Activity: Measured in a cell proliferation assay using TF-1 cells, activity≥2.0×105IU/mg.
Endotoxin: < 0.1 EU per μg of the protein as determined by the LAL method.
Molecular Mass: The recombinant human IL-3 protein consists of 139 amino acids and predicts a molecular mass of 15.9 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.
