[Asn23]-beta-Amyloid (1-42), Iowa mutation, is a biologically active peptide exhibiting increased aggregation propensity and fibril toxicity. This mutation involves the substitution of Aspartic acid (Asp) at position 23 with Asparagine (Asn), contributing to autosomal dominant Alzheimer's Disease in various kindreds due to its association with severe cerebral amyloid beta-protein angiopathy (CAA). Specifically, the mutation is a missense alteration at position 694 of the amyloid precursor protein (APP) gene.

It aggregates and forms typical amyloid fibrils in neutral buffer solution, mirroring those observed with the full-length β-amyloid protein [1].

β-Amyloid (42-1), human TFA, a 42-amino acid peptide, represents the inactive form of Amyloid β Peptide (1-42) and is pivotal in the development of Alzheimer's disease [1].

β-Amyloid (1-40), FAM-labeled TFA is a FAM fluorescently-labelled?β-Amyloid (1-40) peptide (λ ex =?492?nm and λ em =?518?nm) [1] .

Beta-Amyloid(1-14),mouse,rat is a 1 to 14 fragment of Amyloid-β peptide. This peptide is amino acids 1 to 14 fragment of Beta-Amyloid peptide.

β-Amyloid (1-43)(human) TFA exhibits greater aggregation tendencies and heightened toxicity compared to its well-established counterpart, Aβ1-42. Additionally, this compound demonstrates associations with both sAPPα and sAPPβ. It has the potential to serve as an additional biomarker for Alzheimer’s disease (AD), complementing existing markers [1].

β-Melanocyte Stimulating Hormone (MSH), human (Synonyms: Beta-MSH (1-22) (human)) β-Melanocyte Stimulating Hormone (MSH), human, a 22-residue peptide, acts as an endogenous melanocortin-4 receptor (MC4-R) agonist.

Beta-defensin 1, pig TFA, an antimicrobial peptide predominantly located in the tongue mucosa of pigs, exhibits activity against a diverse range of bacteria including Escherichia coli, Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, Bordetella pertussis, and the fungus Candida albicans [1] [2].

β-Amyloid (12-28) (TFA), a peptide fragment of the β-amyloid protein (β1-42)—a 42 amino acid protein primarily found in senile plaque cores—exhibits aggregation properties. This compound holds significance for research into Alzheimer’s disease, highlighting its potential utility in understanding the disease's pathology [1].

His-D-beta-Nal-Ala-Trp-D-Phe-Lys-NH2 TFA, a growth hormone releasing peptide and metabolite of GHRP-1 (Ala-His-D-beta-Nal-Ala-Trp-D-Phe-Lys-NH2), stimulates growth hormone (GH) secretion and elevates intracellular calcium concentration ([Ca2+]i) in rat pituitary gland monolayer cells, without altering cAMP levels [1].

Amyloid β-Protein (33-42) TFA, a fragment encompassing residues 33-42 of the β-amyloid protein, mitigates the toxicity induced by Aβ42 [1].

Beta-defensin 103 isoform X1, pig TFA, is an antimicrobial peptide present in various living organisms, playing a crucial role in the initial defense of their innate immune system against pathogens [1].
