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
CK5, or cytokeratin 5, is a type of intermediate filament protein primarily expressed in the epithelial cells of stratified and transitional tissues. Its expression plays a crucial role in maintaining the structural integrity and stability of these tissues, particularly in response to mechanical stress. The study of CK5 and its recombinant forms has gained significant attention in recent years due to its potential implications in both basic and translational research. Researchers have focused on understanding the molecular mechanisms underlying CK5's involvement in various pathological conditions, such as cancer, where its altered expression may indicate tumor progression or metastasis. Additionally, CK5 is often utilized as a biomarker in diagnosing epithelial tumors and assessing tumor differentiation. Recombinant CK5 proteins have been developed to investigate their functional properties, study protein-protein interactions, and explore therapeutic applications, including regenerative medicine and tissue engineering. Overall, the research on CK5 and its recombinant variants is vital for elucidating the biological roles of this cytokeratin in health and disease, paving the way for novel diagnostic and therapeutic strategies.
