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
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.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
EsxB, a protein component of the Esx secretion system, is a crucial element in the study of mycobacterial biology, particularly in Mycobacterium tuberculosis, the causative agent of tuberculosis. The Esx system, also known as the Type VII secretion system, plays a significant role in the pathogenesis of mycobacteria, facilitating the export of effector proteins that modulate host immune responses and contribute to bacterial survival within macrophages. The understanding of EsxB and its interactions has gained importance in recent years, as it is implicated in host-pathogen interactions and may influence disease progression. Researchers have focused on the structural and functional characterization of EsxB to elucidate its role in virulence and immune evasion. Insights into the mechanisms by which EsxB and its related proteins operate not only enhance our understanding of mycobacterial pathogenesis but also hold potential for developing novel therapeutic strategies and vaccines. Overall, EsxB represents a significant target for understanding the complex interplay between Mycobacterium tuberculosis and the host immune system, paving the way for innovations in tuberculosis treatment and prevention.
