Website: http://www.gtpeptide.com Amyloid β-Protein (31-35) is composed of 5 hydrophobic amino acids, and its water solubility is poor. The synthesis process of Amyloid β-Protein (31-35) is very special, because the five amino acids are all single protected amino acids, so 2-Chlorotrityl Chloride Resin can be selected for synthesis, and the target crude product can be obtained by cracking the ...

Website: http://www.gtpeptide.com When -Glu-Asp- appears at the N-terminal of the sequence, attention should be paid to avoid too alkaline environment and purity reduction during purification. The first two amino acids of the N-terminal of Amyloid β-Protein (22-35) sequence are Glu and Asp. In acid system,Amyloid β-Protein (22-35) will be relatively stable. Amyloid β-Protein (22-35) is a ...

Website: http://www.gtpeptide.com There are many hydrophobic amino acids in the sequence of β-Amyloid (17-40). Because there are no amino acids such as his and Trp, the stability of β-Amyloid (17-40) is good, but the purification is difficult.Go Top Peptide Biotech has a mature purification production system. For some insoluble peptides and peptides that are difficult to separate and purify, ...

Website: http://www.gtpeptide.com Hyperactivity of neurons in specific areas of the brain is thought to be an early disturbance of Alzheimer's disease. The long-term existence of excitatory neurotransmitters in the vicinity of active neurons leads to pathological over stimulation of these neurons, which has a serious impact on the loss of learning and memory in patients with Alzheimer's disease ...
