Active Recombinant Human/Cynomolgus CSF1 protein, His-tagged, Biotinylated

• Cat.No.: CSF1-565HB
• Product Overview: Recombinant Human/Cynomolgus CSF1 protein N-terminal fragment (P09603-1)(Met 1-Asn 190), fused with a polyhistidine tag at the C-terminus, was expressed in HEK293 Cells. The purified protein was biotinylated in vitro.

Specification

• Source: HEK293
• Species: Human, Cynomolgus
• Tag: His
• Predicted N Terminal: Glu 22
• Form: Lyophilized from sterile PBS, pH 7.4, 5% trehalose, 5% mannitol and 0.01% Tween80.
• Bio-activity: Measured in a cell proliferation assay using M‑NFS‑60 mouse myelogenous leukemia lymphoblast cells. The ED50 for this effect is typically 2-10 ng/mL.
• Molecular Mass: The recombinant human / cynomolgus CSF1 consists of 169 amino acids and predictes a molecular mass of 19.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCSF1 is approximately 27-32 kDa band due to glycosylation.
• Endotoxin: < 1.0 EU per μg 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 0.25 mg/ml. Centrifuge the vial at 4°C before opening to recover the entire contents.
• Shipping: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
