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.

Protein Description
Cry2Ab is a bioactive protein derived from the bacterium Bacillus thuringiensis (Bt), known for its insecticidal properties, particularly against lepidopteran pests. The research on Cry2Ab protein primarily focuses on its potential applications in agriculture, specifically in the development of genetically modified (GM) crops that exhibit enhanced resistance to insect herbivores. This resistance is critical for sustainable agriculture, as it can significantly reduce reliance on chemical pesticides, thereby minimizing environmental impact and increasing crop yields. Additionally, studies have shown that Cry2Ab can be effective against various pest species, which makes it a promising candidate for further investigation in biopesticide formulations. Understanding the molecular mechanisms through which Cry2Ab exerts its insecticidal action is essential for optimizing its usage and enhancing its effectiveness in pest management strategies. Research efforts also include investigating the safety profile of Cry2Ab to ensure it does not adversely affect non-target organisms and human health. As a result, the study of Cry2Ab recombinant protein is a vital area of research in the fields of entomology, molecular biology, and agricultural biotechnology, aiming to develop innovative solutions for pest control while promoting ecological balance and food security.
