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
XRCC4 (X-ray repair cross-complementing protein 4) is a crucial component of the non-homologous end joining (NHEJ) pathway, which is a primary mechanism for repairing DNA double-strand breaks. Dysfunction or mutations in the XRCC4 gene can lead to significant genomic instability and contribute to various diseases, including cancer. Research on XRCC4 recombinant protein is pivotal for understanding its role in maintaining genomic integrity and its interactions with other proteins involved in the DNA repair process. By studying XRCC4, scientists aim to elucidate its structural and functional characteristics, which may reveal how it facilitates the assembly and stabilization of repair complexes at DNA break sites. Additionally, the development of XRCC4 recombinant protein provides a valuable tool for biochemical assays, enabling in-depth investigation of the mechanistic details of NHEJ, as well as potential therapeutic targets for enhancing DNA repair in disease contexts. The exploration of XRCC4 also extends to its implications in cellular responses to ionizing radiation and other forms of DNA damage, making it a focal point in both cancer biology and therapeutic development. Thus, the study of XRCC4 recombinant protein not only furthers our understanding of fundamental molecular biology but also opens avenues for novel cancer therapies and interventions in genomic repair mechanisms.
