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
S100B is a member of the S100 protein family, which consists of small, calcium-binding proteins that play crucial roles in various cellular processes, including cell cycle regulation, differentiation, and cellular signaling. S100B is predominantly expressed in astrocytes of the central nervous system (CNS) and is involved in neuroinflammatory responses and neuroprotection. Research has indicated that elevated levels of S100B in the serum or cerebrospinal fluid are associated with various neurological disorders, such as traumatic brain injury, Alzheimer's disease, and multiple sclerosis, making it a potential biomarker for neurological conditions. The recombinant production of S100B protein allows for detailed biochemical studies, including structural analysis and functional assays, which can reveal insights into its role in neurobiology and its pathological implications in brain disorders. Additionally, recombinant S100B can be used to explore therapeutic avenues, such as drug discovery and development, as well as in creating targeted treatments for diseases associated with altered S100B levels. Overall, the study of recombinant S100B protein continues to be a critical area of research in understanding brain function and the molecular mechanisms underlying various CNS pathologies.
