From: Discovery of a bacterial peptide as a modulator of GLP-1 and metabolic disease

Dose dependent activity of HldSe, HldSa and two HldSe mutants, HldSe 24_25insT and HldSe A3Q, on GLP-1 secretion from NCI H716 cells. Peptides were incubated with NCI H716 cells for 2 hours after which GLP-1 levels were measured by ELISA.
