稳定性测试
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.
-
保存条件 & 期限
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.
-
运输条件
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
POLS, or Polymerase θ, is a member of the DNA polymerase family known for its unique role in DNA repair and replication, particularly in the context of double-strand break (DSB) repair. Its distinctiveness lies in its ability to utilize a template-dependent and template-independent mechanism, allowing it to synthesize DNA across damaged regions. This has garnered significant interest within the scientific community due to its implications in genome stability, cancer biology, and potential therapeutic applications. Dysregulation or overexpression of POLS has been associated with various cancers, suggesting that it may play a crucial role in tumorigenesis and therapeutic resistance. Additionally, the study of POLS is crucial for understanding mechanisms such as homologous recombination and non-homologous end joining, both vital for maintaining genetic integrity. Recent advancements in structural biology have provided insights into the enzyme's activity, revealing critical interactions and conformational changes during DNA synthesis. These findings pave the way for potential drug design aimed at targeting POLS in cancer therapy, as inhibiting its function could sensitize tumor cells to DNA-damaging agents. Thus, the ongoing research on POLS is not only pivotal for unraveling fundamental biological processes but also for developing innovative strategies to combat cancer and enhance the efficacy of existing treatments.
