- SynonymLGALS4,L36LBP,Gal-4,Antigen NY-CO-27,Lactose-binding lectin 4
- SourceHuman Galectin-4, His Tag (GA4-H5246) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Ile 323 (Accession # P56470-1).Predicted N-terminus: HisRequest for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 38.1 kDa. The protein migrates as 40-44 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in 50 mM HEPES, 150 mM NaCl, 5 mM EDTA, 2 mM TCEP, pH7.4. Normally trehalose is added as protectant before lyophilization.

- BackgroundGalectin-4 (Gal-4), also known as L36LBP (L-36 lactose-binding protein). The galectins are a family of beta-galactoside-binding proteins implicated in modulating cell-cell and cell-matrix interactions. Galectin-4 expression is concentrated within microvilli in the gastrointestinal epithelium, where it can interact with CD3 and bind activated T cells in the lamina propria during intestinal inflammation. LGALS4 is an S-type lectin that is strongly underexpressed in colorectal cancer.
