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 oppA protein, part of the oligopeptide permease (Opp) system, has garnered significant interest due to its role in bacterial peptide transport and its potential implications in antimicrobial resistance and pathogenesis. OppA is a periplasmic binding protein that plays a crucial role in the uptake of heterogeneous peptides, which are vital for bacterial growth, survival, and virulence. Understanding the mechanisms underlying the peptide transport system can provide insights into how bacteria adapt and proliferate in various environments, including host organisms. Given the rise of antibiotic-resistant strains, exploring oppA and its functional properties offers a pathway to identify novel targets for therapeutic intervention. Furthermore, recombinant expression of oppA protein allows for in-depth structural and functional analyses, facilitating the identification of its binding affinities and conformational dynamics. Studies utilizing recombinant oppA protein not only enhance our comprehension of peptide transport mechanisms but also contribute to the development of innovative strategies to combat bacterial infections, as well as improve our understanding of the evolutionary mechanisms that underpin bacterial adaptability. Overall, the research on oppA recombinant protein is pivotal for both basic science in microbiology and applied biomedical fields, particularly in the context of developing new antimicrobial strategies.
