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
Streptavidin is a tetrameric protein originally derived from the bacterium Streptomyces avidinii, known for its high affinity for biotin, a vitamin essential for various metabolic processes. The unique and robust interaction between streptavidin and biotin has made streptavidin an invaluable tool in biochemical research and biotechnology, particularly in applications such as biosensors, protein purification, and imaging techniques. The study of recombinant streptavidin employs techniques in molecular biology to produce this protein in yeast, bacteria, or mammalian cells, facilitating large-scale production and manipulation. Recombinant protein technology allows for the generation of streptavidin variants with tailored properties, including enhanced stability or altered binding characteristics. Additionally, research into the mechanisms underlying the streptavidin-biotin interaction has implications for drug design, vaccine development, and the development of new therapeutics, given its potential in targeted drug delivery systems. Overall, the investigation of recombinant streptavidin continues to expand its applicability in scientific research and industry, offering innovative solutions to complex biological challenges.
