Target
Human gastric inhibitory polypeptide (GIP) is a 42 amino acid peptide belonging to the glucagon-secretin family of peptide hormones. It is secreted by endocrine cells in the duodenal mucosa and stimulates glucose-dependent insulin secretion as well as GLP-1 release from more distal endocrine (L) cells in the intestinal mucosa. GIP shows amino-acid sequence similarities to glucagon, GLP-1 and GLP-2 (from approximately 50% identity for glucagon to 30% identity for GLP-2).
Application 1
ELISA: ABS 054-26 (as capture antibody) forms a sandwich ELISA pair with ABS 054-24B (as biotinylated detection antibody) for measuring GIP. Detection limit obtained with our non-optimized buffer system is up to 4 ng/mL of GIP (1-42). This pair seems to be also more sensitive then pair ABS 021-04 / ABS 054-24B with our non-optimized buffer system.
