Protein density of SGLT1 in brush border membranes of sglt1 and glut2 wild type mice and appopriate knockout littermates.

BBM were isolated from mucosal scrapings before (basal) and after intragastric glucose gavage (gavage). Samples were stained for SGLT1 and expression levels were quantified by densitometry. Values representing fold changes are expressed as mean ± SEM. Statistical analyses were performed using one-tailed unpaired t-test to compare SGLT1 protein abundance before and after glucose gavage in wild type and knockout mice, respectively. N = 3 mice per group.
