V-9-M Cholecystokinin nonapeptide (Prepro CCK Fragment V-9-M) is a precursor compound of cholecystokinin (CCK). Cholecystokinin (CCK) is a brain-intestinal peptide that stimulates gallbladder contraction and pancreatic exocrine. It can be extracted from the small intestine of dogs and cats and can cause gallbladder contraction.

BSBM7 is an inhibitor of Aβ aggregation and neuronal toxicity.

LPYFD-NH2 acetate shows some inhibitory effect on the aggregation of Abeta(1-42).

β-Amyloid (1-42), rat/mouse TFA is a 42-amino-acid polypeptide fragment that exhibits neurotoxicity to hippocampal slices and is commonly used to establish Alzheimer's disease models for related research.

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.

β-Amyloid (1-37) (human) is potentially associated with mental status in Alzheimer's disease.

The amyloid β-protein is a 39- to 43-amino acid polypeptide that is the primary constituent of senile plaques and cerebrovascular deposits in Alzheimer's disease and Down's syndrome. Additionally it acts as an inhibitor of the ubiquitin-dependent protein degradation in vitro.

β-Amyloid (1-40), FAM-labeled, is a β-Amyloid (1-40) peptide tagged with a FAM fluorescent label, exhibiting an excitation wavelength (λ ex) of 492 nm and an emission wavelength (λ em) of 518 nm.

Biotin-β-Amyloid (1-40) is an amyloid-β-(1-40) peptide with an N-terminal biotinylation.

β-Amyloid (1-38), derived from mice and rats, is a chemical compound comprising 38 amino acids, specifically residues 1-38 of the Aβ peptide. Notably, it serves as the primary constituent of amyloid plaques associated with Alzheimer's disease.
