Amyloid-β (25-35) (Aβ (25-35)) is an 11-residue fragment of the Aβ protein that retains the physical and biological characteristics of the full length peptide. It forms fibrils that react to thioflavin T and Congo red and are organized in a cross-β arrangement of β-strands similar to Aβ (1-40) and Aβ (1-42) fibrils. Aggregated Aβ (25-35) decreases the viability of rat adrenal PC12 cells. It also decreases the viability of primary rat cortical neurons at concentrations ranging from 1 nM to 30 μM. In vivo, intracerebral injection of Aβ (25-35) (20 nmol) in rats induces lesions of neuronal and tissue loss. Aggregated Aβ (25-35) administered intracerebroventricularly to rats induces learning and memory impairments in the Y-maze, novel object recognition, and contextual fear conditioning tests.
Glucagon-like peptide 1 (1-37), human (TFA), is a highly potent agonist of the GLP-1 receptor and is a pancreatic hormone synthesized through post-translational processing of proglucagon.
Glucagon-like peptide 1 (1-37), human, is a highly potent agonist of the GLP-1 receptor and a pancreatic hormone synthesized through post-translational processing of proglucagon. Unlike truncated forms of GLP-1, it has no effect on food intake in rats.
CNP, a member of the natriuretic peptide family, was first identified in porcine brain and later found in other mammals as well as non-mammals. Processing of the CNP precursor gives rise to CNP-22 and its N-terminally elongated form, CNP-53. The CNPs shar
Atrial Natriuretic Peptide (1-28), human, porcine, Biotin-labeled, is one of three mammalian natriuretic peptides (NPs) that exerts endocrine effects on fluid homeostasis and blood pressure. Atrial Natriuretic Peptide holds promise for cardiovascular diseases research.
This human neuropeptide of the RFamide peptide family with orexigenic activity may be also involved in the control of feeding behavior. The 26RFa gene is exclusively expressed in the ventromedial hypothalamic nucleus and in the lateral hypothalamic area.
Corticotropin-releasing factor human (Human CRF; Human corticotropin-releasing factor) is an immunomodulatory neuropeptide that releases ACTH from the anterior pituitary and stimulates the sympathetic nervous system and adrenal medulla.
Glucagon-like peptide 2 (GLP-2) is a recently identified intestinal epithelium-specific growth factor that has been shown to reduce the severity of inflammatory disorders of the intestine in rodent models. Currently Glucagon-Like Peptide 2 is used as a po
Proinsulin C-Peptide (31-63), porcine, is a peptide derived from the cleavage of porcine proinsulin, specifically spanning the 31st to 63rd amino acid residues.
