Target
-
Function
Galactose-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 specificity
A major expression is found in the colonic epithelium. It is also abundant in the activated macrophages. -
Sequence similarities
Contains 1 galectin domain. -
Cellular localization
Nucleus. Cytoplasmic in adenomas and carcinomas. May be secreted by a non-classical secretory pathway and associate with the cell surface. - Information by UniProt

Western blot - Anti-Galectin 3 antibody (ab31707)
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.

Immunocytochemistry/ Immunofluorescence - Anti-Galectin 3 antibody (ab31707)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.
