β-Amyloid (1-42) (Amyloid β-peptide (1-42), human TFA, a 42-amino acid peptide that has not been treated with HFIP, is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human TFA remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human TFA, after being monomericized by HFIP and dissolved in DMSO to form the stock solution, on the one hand, can form soluble oligomers (AβOs) when incubated at 4 °C, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37 °C to form insoluble fibrils, with lower neurotoxicity, and participating in the oxidative damage process. Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death .

CAS No.: 42935-17-1
Purity:  ≥95.0%
Synonyms: PGH2
Prostaglandin H2 (PGH2) is an endothelium-derived contracting factor. Prostaglandin H2 can cause vasoconstriction. Prostaglandin H2 is the common precursor of all PGs and is produced by several cells that express cyclooxygen-ases. Prostaglandin H2 can activate PGD2 receptors CRTH2 and DP via interacting directly with the receptors and/or by giving rise to PGD2 after catalytic conversion by plasma proteins. Prostaglandin H2 can induce eosinophils migration and inhibit platelet aggregation. Prostaglandin H2 can accelerate the formation of dimers and higher oligomers of amyloid β1-42. Prostaglandin H2 can be used for the researches of inflammation and neurological disease, such as Alzheimer disease .

Synonyms: Citrullinated Aβ (1-42); Citrullinated Aβ42
Target:  

Amyloid-β

Research Areas:  

Neurological Disease

Citrullinated amyloid-β (1-42) peptide (human) (Citrullinated Aβ (1-42)) is a modified form of β-Amyloid (1-42) (HY-P1363) with a citrullination at the Arg5 site. Compared to the unmodified β-Amyloid (1-42), its formation of soluble low-molecular-weight oligomers is enhanced, the rate of fibril formation is reduced, and like unmodified Aβ42, it forms protofibrils comprised of parallel β-sheets .

Amyloid-β Tau Protein

Research Areas:  

Neurological Disease

(Pyr3)-Amyloid β-Protein (3-42) is an N-terminally truncated pyroglutamylated β-amyloid peptide. (Pyr3)-Amyloid β-Protein (3-42) forms stable β-sheet structures across different pH values, co-oligomerizes with Aβ1-42 to form cytotoxic oligomers, induces tau-dependent cytotoxicity and neuronal loss, inhibits hippocampal LTP, and exhibits stronger protease resistance. (Pyr3)-Amyloid β-Protein (3-42) exists in the brain tissues of human Alzheimer's disease patients, correlates with the pathogenesis of Alzheimer's disease, and follows a unique, faster oligomerization pathway. (Pyr3)-Amyloid β-Protein (3-42) can be used in Alzheimer's disease-related research .
