[Arg6]-β-Amyloid (1-40), England mutation 是具有生物活性的肽,与多种家族性常染色体显性阿尔茨海默病相关。特别地,这种英国突变,即位于第6位的His被Arg所替换,已报告可提高寡聚体形成动力学,加速初级纤维的种子化过程。此类寡聚体对神经元培养细胞展现出较高毒性。
β-Amyloid (29-40), a fragment of the Amyloid-β peptide, possesses physical and chemical properties similar to those of viral protein fusion peptides. The C-terminal fragments (29-40 42) of Alzheimer's betaamyloid peptide can induce the fusion of liposomes.
This synthetic peptide consists of amino acids 22 to 40 of betaamyloid protein. This peptide sequence is often used in betaamyloid structure and aggregation studies.
Gp100 (25-33), human TFA is a 25-33 amino acid fragment of human melanoma antigen.Gp100 (25-33), human TFA is a 9-amino acid (AA) epitopes restricted by h-2db and recognized by T cells.
