| Description |
This peptide is well suited to the quantitative determination of A 42 peptide. Alzheimerâs disease (AD) is characterized by the presence of extracellular plaques and intracellular neurofibrillary tangles (NFTs) in the brain. The major protein component of these plaques is beta amyloid peptide (A), a 40- to 43- amino-acid peptide cleaved from amyloid precursor protein by secretase (BACE) and a putative (gamma) secretase. Increased release of the âlonger formsâ of A peptide, A 42 and A 43, which have a greater tendency to aggregate than A 40, occurs in individuals expressing certain genetic mutations, expressing certain ApoE alleles or may other, still undiscovered factors. |

| Notes |
This product is a chemically-modified β-amyloid (1-42) precursor, which belongs to GenScriptâs "click peptides".
The "click peptides" are best described by the following key features:
1. Enhanced StabilityâThe O-acyl moiety within the click peptide is stable even under acidic pH.
2. Convenient and quick processâThe "click peptides" can be easily converted to native peptide at pH 7.4 or above.
3. No by-product formation in the conversion process
4. High Solubilityâ15 mg/ml for click peptide in water compared to 0.14 mg/ml for the native peptide.
5. Superior qualityâAfter the "click", the aggregative property of the peptides is significantly minimized compared to its native format. |
