Our Abpromise guarantee covers the use of ab31707 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 1 µg/ml.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 30 kDa (predicted molecular weight: 26 kDa).|
FunctionGalactose-specific lectin which binds IgE. May mediate with the alpha-3, beta-1 integrin the stimulation by CSPG4 of endothelial cells migration. Together with DMBT1, required for terminal differentiation of columnar epithelial cells during early embryogenesis.
Tissue specificityA major expression is found in the colonic epithelium. It is also abundant in the activated macrophages.
Sequence similaritiesContains 1 galectin domain.
Cellular localizationNucleus. Cytoplasmic in adenomas and carcinomas. May be secreted by a non-classical secretory pathway and associate with the cell surface.

Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
Lane 2: Galectin 3 knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lane 4: MCF7 whole cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab31707 observed at 32 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab31707 was shown to specifically recognize Galectin 3 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when Galectin 3 knockout samples were examined. Wild-type and Galectin 3 knockout samples were subjected to SDS-PAGE. Ab31707 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1 ug/ml and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
ICC/IF image of ab31707 stained human HeLa cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab31707, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

Predicted band size: 26 kDa
Observed band size: 30 kDa why is the actual band size different from the predicted?
We also see a very faint band at 52 kDa in the HeLa Whole cell lysate, we are uncertain as to the identity of this band.
