Not tested
Protein Concentration
25µg size is bottled at 0.2mg/mL concentration. 100 µg size is supplied at a lot-specific concentration.
Storage and Handling
Briefly centrifuge the vial upon receipt. An unopened vial can be stored at 4°C for up to 2 weeks, or at -20°C or below for up to six months. The protein may be further diluted to 0.1 mg/mL using 0.22 µm-filtered PBS buffer (pH 7.4). For long-term storage, the diluted stock solution should be aliquoted and stored at ≤ –70°C to minimize freeze-thaw cycles. If additional dilution is required, carrier proteins such as FBS or BSA should be added to maintain protein stability.
Background Information
Notum is a secreted carboxylesterase enzyme that acts as a negative regulator of the Wnt signaling pathway. It plays a crucial role in development, tissue homeostasis, and regeneration by modulating Wnt activity. Notum inhibits Wnt signaling by removing an essential lipid modification (palmitoleate) from Wnt proteins, in this manner preventing their binding to receptors and subsequent activation of downstream pathways. Dysregulation of Notum has been linked to various diseases, including cancer and degenerative disorders, making it a promising target for therapeutic intervention..
