Mouse Galectin-4, His tag (GA4-M5247) is expressed from human 293 cells (HEK293). It contains AA Met 1 - Ile 326 (Accession # Q8K419-1).

Predicted N-terminus: His

Molecular Characterization

Galectin-4(Met 1 - Ile 326)Q8K419-1

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 38.6 kDa. The protein migrates as 44 kDa and 45-46 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.


Less than 1.0 EU per μg by the LAL method.


>92% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in 50 mM HEPES, 150 mM NaCl, pH7.4. Normally trehalose is added as protectant before lyophilization.

Galectin-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.
