稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Protein Description
The study of the Ab1-42 recombinant protein is deeply rooted in Alzheimer's disease research, as this peptide is a significant component of amyloid plaques, which are characteristic of this neurodegenerative disorder. Ab1-42 is a derivative of the amyloid precursor protein (APP) and is known for its propensity to aggregate into fibrils, contributing to neuronal toxicity and cognitive decline observed in Alzheimer’s patients. Understanding the structure, aggregation dynamics, and biological effects of Ab1-42 is crucial for elucidating the pathophysiological mechanisms underlying the disease. Recombinant expression systems have been developed to produce Ab1-42 in a controlled manner, allowing for detailed biochemical and biophysical studies. These investigations aim to elucidate the mechanisms of aggregation, identify potential therapeutic targets, and evaluate the peptide's interactions with biological membranes and cellular components. Research has also focused on the development of inhibitors that can prevent Ab1-42 aggregation or promote its clearance, representing a potential avenue for therapeutic intervention. By gaining insights into the fundamental properties of Ab1-42, researchers hope to pave the way for innovative treatments that could mitigate or prevent the progression of Alzheimer’s disease, ultimately improving the quality of life for patients and their families.
