Function
Binds galactosides. Has high affinity for the Forssman pentasaccharide. May play a role in thymocyte-epithelial interactions relevant to the biology of the thymus. Inhibits cell proliferation. It is a ligand for HAVCR2/TIM3. Induces T-helper type 1 lymphocyte (Th1) death. Isoform Short acts as an eosinophil chemoattractant. -
Tissue specificity
Peripheral blood leukocytes and lymphatic tissues. Overexpressed in Hodgkin disease tissue. -
Sequence similarities
Contains 2 galectin domains. -
Domain
Contains two homologous but distinct carbohydrate-binding domains. -
Cellular localization
Cytoplasm. Secreted. May also be secreted by a non-classical secretory pathway. - Information by UniProt

Lanes 1-4 : Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) at 1/50000 dilution
Lanes 5-7 : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/50000 dilution
Predicted band size: 40 kDa
Observed band size: 15,36,40 kDa why is the actual band size different from the predicted?Blocking and diluting buffer and concentration: 5% NFDM/TBST.
Bands of 40KDa and 36KDa respectively represent two different isoforms.
Band of 15KDa may represents the cleaved form.
The molecular weight observed is consistent with what has been described in the literature (PMID: 9038233, 11886844, 22805533, 15811318).
Low expression: mouse brain (PMID: 9038233).
Samples are non-boiled as boiling may cause protein aggregates.
Exposure time: Lanes 1-2: 5.5 seconds; Lanes 3-6: 37 seconds; Lanes 7: 3 minutes.

Confocal image showing membranous and cytoplasmic staining in EL4.IL-2 cell line. The staining pattern observed is consistent with what has been described in the literature (PMID: 28750861). ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor® 594) was used to counterstain tubulin at 1/200 dilution (Red). The nuclear counterstain was DAPI (Blue).
Secondary antibody only control: Secondary antibody is ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) at 1/1000 dilution.
