General description

Galectins specifically bind to β-galactosides. 15 mammalian galectins have been identified so far. Galectin 8 contains two CRDs connected by a short linker peptide.
Monoclonal Anti-Galectin 8 (mouse IgM isotype) is derived from the hybridoma VA-11.25 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a recombinant rat galectin 8.Galectins belong to a family of carbohydrate-binding proteins. Within this family of proteins, galectin 8 is unique, as it exists in many forms encoded by the same gene.

Specificity

The antibody has low cross-reactivity with galectin 3 and galectin 9.

Immunogen

recombinant rat galectin 8.

Application

Monoclonal Anti-galectin-8 antibody produced in mouse has been used for:
  • immunoblotting
  • immunocytochemistry
  • enzyme linked immunosorbent assay (ELISA)

Biochem/physiol Actions

Galectins belong to a family of carbohydrate-binding proteins. These proteins share similarities in the carbohydrate recognition domain (CRD) and in their specificity for N-Acetyllactosamine-enriched glycoconjugates. The binding of galectins to saccharides modulates cell proliferation, cell death and cell migration, which are involved in cancer initiation and progression. Galectin 8 is a secreted protein that requires both of its CRDs to be active to modulate cell adhesion. It forms a complex with integrins and triggers integrin-mediated signaling cascades. On the contrary, excessive amounts of this protein negatively regulate cell adhesion by interacting with integrins. These signals assist in identifying regions available for cell adhesion and migration. It may be involved in neoplastic transformation.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Galectins constitute a family of evolutionarily conserved animal lectins, which are defined by their affinity for poly-N-acetyllactosamine-enriched glycoconjugates and sequence similarities in the carbohydrate recognition domain. During the past decade, attempts to dissect the functional role for galectins in vivo

Galectins form a family of carbohydrate-binding proteins defined by their affinity for beta-galactosides containing glycoconjugates. The carbohydrate recognition domain (CRD) is responsible for the specificity of galectins for saccharides. This binding may result in modulated cell proliferation, cell death and

We previously showed that tandem-repeat type galectin-8, which has two covalently linked carbohydrate recognition domains (CRDs), induces neutrophil-adhesion through binding to integrin alphaM. Here, we analysed the function of galectin-8 in Jurkat T-cells. Galectin-8, as well as tandem-repeat galectin-9, and

The interaction of cells with the extracellular matrix regulates cell adhesion and motility. Here we demonstrate that different cell types adhere and spread when cultured in serum-free medium on immobilized galectin-8, a mammalian beta-galactoside-binding protein. At maximal doses, galectin-8 is
