Active Recombinant Human CSF1R protein, Fc-His-tagged

• Cat.No.: CSF1R-39H
• Product Overview: Active Recombinant Human CSF1R protein(Met 1-Glu512)(NP_005202.2) precursor was expressed in HEK293 with the fused C-terminal polyhistide-tagged Fc region of human IgG1 at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc&His
• Protein Length: 1-512 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: 1. Measured by its ability to bind biotinylated Human CSF1-his in functional ELISA. 2. Measured by its ability to inhibit the human CSF-induced proliferation of MNFS60 mouse myelogenous leukemia lymphoblast cells. The ED50 for this effect is typically 0.1-0.6 μg/mL in the presence of 3 ng/ml Recombinant Human M-CSF.
• Molecular Mass: The recombinant human M-CSFR/Fc chimera is a disulfide-linked homodimer protein. The monomeric subunit contains 737 amino acids after the removal of signal peptide with a calculated molecular mass of 82.4 kDa. As a result of glycosylation, the monomer migrates as an approximately 115-125 kDa protein in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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.
