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
The study of IPO4 (Importin 4) recombinant protein is critical due to its role in cellular transport mechanisms, particularly in the nuclear import of proteins containing nuclear localization signals (NLS). IPO4 is a member of the importin beta superfamily, functioning as a transporter that facilitates the translocation of various cargo proteins across the nuclear envelope. This process is vital for regulating numerous cellular functions, including gene expression, cell cycle progression, and signal transduction. Research has shown that abnormalities in the functioning of IPO4 can be linked to various diseases, including cancer and neurodegenerative disorders, highlighting the importance of understanding its mechanisms. Producing IPO4 as a recombinant protein allows for detailed biochemical and biophysical studies, enabling researchers to elucidate its interaction with cargo proteins, nucleoporins, and other key nuclear transport components. Furthermore, an in-depth characterization of IPO4 could lead to the development of novel therapeutic strategies that target nuclear transport pathways in disease contexts. Therefore, the exploration of IPO4 recombinant protein not only contributes to fundamental biological knowledge but also holds potential therapeutic implications, making it a significant area of investigation in molecular and cellular biology.
