Product and properties Synonyms CD115; CSFR; CSF-1-R; M-CSF R Source Mouse M-CSF R/CSF1R/CD115 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ala20-Ser511.[Accession | P09581] Molecular Weight The protein has a predicted MW of 56.3 kDa. Due to glycosylation, the protein migrates to 76-82 kDa based on Tris-Bis PAGE result. Endotoxin Less than 1EU per μg by the LAL method. Purity > 95% as determined by SDS-PAGE Activity SPR Data: Mouse M-CSF R, His tag captured on CM5 Chip via Anti-His Antibody can bind Human M-CSF, No tag with an affinity constant of 1.70 nM as determined in SPR assay . Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. Storage The product should be stored at -25~-15℃ for 1 year from date of receipt. 2-7 days, 2 ~ 8 °C under sterile conditions after reconstitution. 3 -6 months, -85~-65℃ under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
