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.

Protein Description
OmpA (Outer Membrane Protein A) is a well-studied protein found in the outer membrane of various Gram-negative bacteria, including Escherichia coli. It plays a crucial role in maintaining the structural integrity of the bacterial membrane and is involved in important physiological processes such as nutrient transport and adhesion to surfaces. The study of OmpA has gained significant attention due to its potential applications in vaccine development, as it can elicit strong immune responses. Recombinant OmpA protein has been generated through molecular cloning and expression techniques, allowing researchers to obtain large quantities of this protein for further analysis. The investigation of OmpA also contributes to our understanding of bacterial pathogenesis, as its expression levels can influence virulence factor production and biofilm formation. Moreover, OmpA serves as a model for studying protein folding and membrane insertion, providing insights into the broader mechanisms of outer membrane assembly in bacteria. The ongoing research on OmpA recombinant protein explores its structural properties, immunogenicity, and potential as a target for novel antibacterial therapies, making it a significant focus in microbiology and immunology.
