Apexbio Technology LLC Amyloid β-Peptide (1-42) (human),1mg CAS# 107761-42-2
Supplier: Apexbio Technology LLC B60571
Amyloid β-Peptide (1-42) (Aβ42) human is a 42-amino acid peptide that plays a key role in the pathogenesis of Alzheimer disease (AD) [1].The main deleterious effects in the pathogenesis are probably regulated by Aβ42, which acts as a repressor or activator of gene transcription causing further synaptic function damage and neuronal degeneration [2].Aβ42 reduced the viability of SH-SY5Y cells to 65% when it rose to 2.5 μM. Using the chromatin immunoprecipitation (ChIP) and qRT-PCR assays, treatment of SH-SY5Y cells with Aβ42 associated peptide with both LRP1 and KAI1 promoters and increased APP mRNA levels, while the nontoxic Aβ42 G33A peptide, as a control group which presents in the nucleus abundantly, did not have any influence on mRNA expression. The exclusive increase of transcription and expression of its precursor gene APP was found with the treatment of Aβ42, compared with several different lengths of peptides [1]. Other sizes are also available. Please inqury us for quote.
