Amyloid β - protein (1-43) is one of the longest sequences in β - Amyloid protein series. This kind of long peptide will be more difficult in solid-phase synthesis. The main difficulty is the difficulty of sequence synthesis and the folding with the extension of peptide chain. At the same time, t

Based on the sequence of β-Amyloid Protein, a lot of changes have been made to the Amyloid Bri Protein,The addition of Cys and the formation of disulfide bond make the research effect of Amyloid Bri Protein different. There are three glutamic acids in the Amyloid Bri Protein (1-23) sequence, whic
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,
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) w
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 pept
The spatial structure of the amino acid composed of Amyloid β-Protein (16-20) is simple, and there is almost no secondary structure folding. In the process of production, we can use Boc chemical synthesis, choose H-Phe-Phe-OH and other raw materials to design a reasonable production plan, which c
Alzheimer's disease (AD) is the most common neurodegenerative disease. β - amyloid protein can oligomerize, aggregate and then form the neurotoxic fragments of plaque. Clinical manifestations include the presence of intracellular nerve fiber tangles and extracellular amyloid plaques, which can lead
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 l
For the fragment of β - amyloid protein (a β), the middle 15 amino acids were selected from the amino acids of the amino acids. During the production, whether in the process of solid-phase synthesis or separation and purification, the production difficulty of theAmyloid β-Protein (6-20) decreased a
There are two main pathological features of Alzheimer disease (AD) which are still at a loss: amyloid plaques formed by misfolded amyloid β-protein,Aβ deposition in the brain and nerve fiber tangles caused by over phosphorylation of Tau protein. In the process of continuous research on amyloid β-pro
Amyloid β - protein (4-42) is a fragment of β - amyloid protein, the reduction of sequence reduces the difficulty of synthesis, and the solubility is relatively better. In terms of storage conditions and half-life, there was no difference between the Amyloid β-Protein (4-42) and other β - amyloid pr
For a long time, the deposition of Aβis the main cause of degeneration and death of neurons around the senile plaques in AD patients. The deposition of Aβis not only related to the degeneration of neurons, but also can activate a series of pathological events, including the activation of astrocytes
It has been proved that A β 1-42 is more toxic and easier to aggregate, thus forming the core of a β precipitate and causing neurotoxicity. In order to promote the research and cure of Alzheimer's disease, it selected 38 amino acid fragments (3-40) of a β 1-42 for further study. In general, a β is p
Amyloid β - protein (1-46) is a kind of β-Amyloid peptide. The peptide sequence up to 46 peptide makes the synthesis and purification of this peptide more difficult. At the same time, in terms of solubility, this peptide is more difficult to dissolve in water. The study of this long peptide is more
