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).
Synthetic human gastric inhibitory polypeptide coupled to carrier.
ABS 021-04 binds human GIP. ABS 021-04 cross-reacts up to 10% with PACAP and human GLP-2 but <0.1% with glucagon, GLP-1 or VIP. Cross-reactivity with porcine GIP has not been determined.
Not determined
The dilution guideline applies to glutaraldehyde-linked GIP-OA (molar ratio 4:1) coated at 1 µg/mL. With GIP coated directly at 2 µg/mL the dilution guideline is 1/2000. In addition ABS 021-04 binds free GIP in solution.
