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
TSPAN4 (tetraspanin 4) is a member of the tetraspanin family, which includes proteins characterized by their four membrane-spanning domains and their ability to form complexes with various proteins, including integrins and signaling molecules. Research into TSPAN4 has gained traction due to its roles in several biological processes, including cell adhesion, migration, and proliferation. It is particularly implicated in immune responses and has been shown to interact with immune-related proteins, suggesting a potential role in modulating immune cell function and responses. Additionally, TSPAN4 has been associated with various diseases, including cancer and neurodegenerative disorders, making it a target of interest for therapeutic interventions. The expression and activity of TSPAN4 can vary significantly in different tissues and under various physiological conditions, highlighting its importance in health and disease. To better understand its functions and mechanisms, researchers have developed recombinant TSPAN4 proteins, which enable the study of its biochemical properties, interaction with binding partners, and overall cellular effects. These studies are crucial for elucidating the role of TSPAN4 in cellular processes and its potential applications in clinical settings.
