Immunoprecipitation (IP) is a technique used to enrich protein antigens from a complex mixture using specific antibodies. To carry out an IP, antibodies must be coupled to a solid substrate, such as agarose resin or magnetic beads, to allow for

Phosphopyruvate hydratase, usually known as enolase, is a metalloenzyme (EC 4.2.1.11) that catalyses the conversion of 2-phosphoglycerate (2-PG) to phosphoenolpyruvate (PEP), the ninth and penultimate step of glycolysis. The chemical reaction is:2-phospho-D-glycerate ⇌ phosphoenolpyruvate + H2O Phosphopyruvate hydratase belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of

Gastric inhibitory polypeptide or gastric inhibitory peptide also known as glucose-dependent insulinotropic polypeptide abbreviated as GIP, is an inhibiting hormone of the secretin family of hormones. Meier JJ, Nauck MA (2005). "Glucagon-like peptide 1(GLP-1) in biology and pathology". Diabetes/Metabolism Research and Reviews. 21 (2): 91–117. doi:10.1002/dmrr.538. PMID 15759282. S2CID 39547553. While it is a weak inhibitor of gastric acid secretion, its main role

Gastrin-releasing peptide, also known as GRP, is a neuropeptide, a regulatory molecule that has been implicated in a number of physiological and pathophysiological processes. Most notably, GRP stimulates the release of gastrin from the G cells of the stomach. The gene from which GRP is derived encodes a number

Neuromedin U (or NmU) is a neuropeptide found in the brain of humans and other mammals, which has a number of diverse functions including contraction of smooth muscle, regulation of blood pressure, pain perception, appetite, bone growth, and hormone release. It was first isolated from the spinal

Neuromedin N is a neuropeptide derived from the same precursor polypeptide as neurotensin, and with similar but subtly distinct expression and effects. Carraway RE, Mitra SP, Spaulding G (1992).

Neuromedin B (NMB) is a bombesin-related peptide in mammals. Ohki-Hamazaki H (October 2000).

Bombesin is a 14-amino acid peptide originally isolated from the skin of the European fire-bellied toad (Bombina bombina) by Vittorio Erspamer et al. and named after its source.
