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
SDSL (Site-Directed Spin Labeling) is a powerful technique utilized in the field of structural biology to investigate the dynamics and conformational changes of proteins. This method primarily involves attaching stable free radical spin labels to specific sites on proteins, allowing researchers to study the local environment, interactions, and conformational states through electron paramagnetic resonance (EPR) spectroscopy. The unique advantage of SDSL lies in its capacity to provide insight into membrane proteins, which are often challenging to analyze due to their complex structures and environments. The quest to understand protein folding, dynamics, and interactions under physiological conditions has made SDSL an invaluable tool in modern biochemistry. Researchers have increasingly focused on integrating SDSL with complementary techniques such as X-ray crystallography and NMR spectroscopy to achieve a comprehensive understanding of protein structures. The advances in protein engineering techniques have facilitated the selective incorporation of spin labels, thereby enhancing the specificity and sensitivity of SDSL studies. Thus, SDSL continues to play a crucial role in deciphering the intricate mechanisms governing protein function, contributing to our broader understanding of biological processes and potential therapeutic interventions.
