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.

背景信息
Beta-lactamase CTX-M-1 is a pivotal enzyme responsible for the resistance of bacteria to beta-lactam antibiotics, including penicillins and cephalosporins. Its emergence is primarily linked to the spread of Extended-Spectrum Beta-Lactamases (ESBLs) in Enterobacteriaceae, which has led to increased treatment failures in infections caused by these pathogens. The CTX-M-1 gene is widely disseminated among various bacterial species, posing a significant public health threat. Research on the recombinant protein of CTX-M-1/Bla is crucial for understanding the mechanism of antibiotic resistance, as it can provide insights into enzyme structure-function relationships and the dynamics of resistance gene transfer. Furthermore, characterizing this recombinant protein can facilitate the development of novel inhibitors to combat beta-lactamase activity and enhance the efficacy of existing antibiotics. The recombinant production also allows for high-yield studies that can inform drug design and the implementation of alternative therapeutic strategies. Identifying the factors contributing to the spread and effectiveness of CTX-M-1 may prove instrumental in addressing the growing challenge of antibiotic resistance in clinical settings.
