Biotin-amyloid-β (1-42) peptide is an affinity probe that allows amyloid-β (1-42) (Aβ42) to be detected or immobilized through interaction with the biotin ligand. It has been used to identify Aβ42 interaction partners in rat hippocampal synaptosomal membranes.
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.
Amyloid (1-42), rat is a polypeptide composed of 42 amino acids. It is toxic to hippocampal slices and can be used in the study of alzheimer's disease.
Amylin (8-37), rat, is a truncated analog of native Amylin that selectively inhibits insulin-related glucose uptake and glycogen deposition in muscle tissue. Also known as islet amyloid precursor peptide (IAPP), Amylin is co-secreted with insulin.
β-Amyloid (1-42), rat TFA is a 42-aa peptide, shows the effects of cytotoxicity on acute hippocampal slices, and has been used in studies of alzheimer's disease.
