The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 10 µg/ml.
1/50 - 1/100. Predicted molecular weight: 32 kDa.
1/10 - 1/50.
FunctionIGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
Tissue specificityExpressed by most tissues. Present in plasma.
ab76001 at 1/50 dilution, staining IGFBP3 in human breast carcinoma tissue section by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections). The DAB staining procedure was used for detection.
ICC/IF image of ab76001 stained HeLa cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab76001, 10µg/ml) overnight at +4°C. The secondary antibody (green) was for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
