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
CENPQ is a protein that plays a crucial role in the assembly and maintenance of the centromere, a vital region of chromosomes responsible for proper segregation during cell division. Research into CENPQ has gained significance due to its implications in genomic stability and its potential association with various diseases, including cancer. As a part of the centromere complex, CENPQ interacts with other centromeric proteins, contributing to the formation of the kinetochore, which is essential for the accurate alignment and distribution of chromosomes during mitosis and meiosis. The study of CENPQ and its functional mechanisms is imperative to understand how disruptions in centromere dynamics can lead to aneuploidy and tumorigenesis. Recent advancements in molecular biology techniques, such as CRISPR-Cas9 for gene editing and advanced imaging methods for observing protein interactions in live cells, have facilitated a more profound investigation into CENPQ’s role. Understanding its structure, function, and interaction network not only sheds light on fundamental cellular processes but may also reveal novel therapeutic targets for diseases linked to chromosomal instability. Given the critical nature of centromeres in maintaining genetic integrity, ongoing research into CENPQ is vital for delineating its contribution to chromosome biology and the potential consequences of its dysregulation in human health.
