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
CHEK1, a key protein kinase in the cell cycle checkpoint pathways, plays a critical role in maintaining genomic stability by responding to DNA damage and ensuring proper cell division. This enzyme, part of the ATR (ATM and Rad3-related) signaling cascade, is activated in response to various cellular stresses, including DNA replication stress and double-strand breaks. Mutations or dysregulation of CHEK1 have been implicated in various cancers, making it a potential target for therapeutic interventions. Researchers have focused on the recombinant production of CHEK1 to study its biological functions, regulatory mechanisms, and interaction with other proteins. By using techniques like bacterial expression systems and eukaryotic cell lines, scientists aim to generate functional CHEK1 to investigate its role in checkpoint signaling and cell cycle control. Understanding CHEK1's structure and function through recombinant protein studies may lead to novel insights into cancer biology and the development of new cancer therapies that exploit the vulnerabilities of tumor cells with compromised checkpoint responses. Consequently, the research on CHEK1 not only enhances our understanding of fundamental cellular processes but also contributes to the advancement of targeted cancer treatments.
