Source |
Biotinylated Human M-CSF R/CSF1R/CD115 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Ile20-Glu512.[Accession | P07333-1] |
|
Molecular Weight |
The protein has a predicted MW of 57.4 kDa. Due to glycosylation, the protein migrates to 75-105 kDa based on Tris-Bis PAGE result. |
|
Endotoxin |
Less than 1EU per μg by the LAL method. |
|
Purity |
> 95% as determined by Tris-Bis PAGE and HPLC |
|
Activity |
ELISA Data: Immobilized Anti-CSF R Antibody, hFc Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Human M-CSF R, His Tag with the EC50 of 27.7ng/ml determined by ELISA. SPR Data: Biotinylated Human M-CSF R, His-Avi Tag immobilized on CM5 Chip can bind Human M-CSF, No Tag with an affinity constant of 0.81 μM 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. |
