Proteins Casein protein [129], whey proteins [130], peptones [131], and different amino acids such as l-glutamine [132], l-phenylalanine [133], L-tryptophan [134], and l-arginine induce GLP-1 secretion through activation of the calcium-sensing receptor (CaSR), the taste receptor TAS1R1/TAS1R3, G-protein-coupled receptor 6A (GPRC6A) [135], GPR142, peptide transporter-1 (PEPT1) [136], and amino acid (AA) transporter [137] (Fig
This resin works well with small and large proteins tagged with GST in batch or column purifications (Low Flow)
GLP-1, together with GIP, is responsible for the incretin effect, since it binds to GLP-1 receptor in -cells in the pancreas leading to an increase in intra-cellular Ca and a subsequent insulin secretion in response to glucose (Reference Vilsbll and Holst11)

They require a transport system known as the carnitine shuttle
