Stability Test
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.
-
Storage & Shelf Life

Protein Description
YstB is a protein of interest due to its role in various biological processes and potential applications in biotechnology and medicine. As a member of the Yersinia pestis multi-gene family, YstB is believed to play a significant role in the virulence of this pathogenic bacterium. Understanding the structure and function of YstB can provide insights into the mechanisms of disease caused by Yersinia species, thereby aiding in the development of therapeutic interventions. The recombinant expression of YstB allows researchers to study its properties in detail, enabling the investigation of its interactions with other cellular components and its impact on immune responses. Furthermore, YstB has been suggested as a candidate for vaccine development, promising to enhance protective immunity against infections caused by Yersinia. By harnessing advanced molecular biology techniques for the cloning and expression of the ystB gene, scientists can produce large quantities of the protein for detailed functional studies. This research not only advances our understanding of bacterial pathogenesis but also holds potential for the development of novel strategies to combat infectious diseases. The findings derived from YstB research could pave the way for innovations in vaccine design and therapeutic approaches, highlighting the protein's significance in both microbiological and medical research contexts.
