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
TOP3B is a member of the topoisomerase family, which plays a crucial role in DNA replication and repair by alleviating torsional strain in the DNA helix. Research on TOP3B has gained momentum due to its involvement in critical cellular processes and its potential links to various diseases, including cancer. Unlike other topoisomerases, TOP3B specifically interacts with RNA and is implicated in the regulation of transcription by forming complexes with RNA-binding proteins. Its unique function in modulating RNA metabolism makes it an intriguing target for understanding how dysregulation of this process can contribute to tumorigenesis and other pathologies. Recent studies have highlighted the protein's role in maintaining genomic stability and its importance in cellular responses to stress. Furthermore, the exploration of TOP3B's biochemical properties and regulation mechanisms could provide insights into novel therapeutic approaches, especially in the context of cancer treatment where topoisomerase inhibitors have been successfully employed. Overall, the investigation of TOP3B's functions and interactions within the cell is vital for unraveling the complexities of gene expression regulation and its implications in disease.
