Biological Activity

Purity: > 95% as determined by reduced SDS-PAGE.
Endotoxin :LAL determination: less than 0.001 ng/ug (0.01 EU/ug).
Storage: Freeze-dried protein should be stored at < -20°C, but at room temperature for up to 3 weeks. The recombinant protein solution can be stored at 4-7℃ for 2-7 days. The isometric solution of the recombinant sample was stable at < -20°C for 3 months.

Biological activity: DickkopF-related protein 1(DKK-1) is a member of the DickkopF family. The protein secreted by DKK1 has two cysteine-rich regions separated by junction regions. It antagonizes typical Wnt signaling by inhibiting lRP5/6 interaction with Wnt and forming ternary complexes with transmembrane protein KREMEN that promote lRP5/6 internalization. In adults, Dkks has been associated with bone formation and bone disease, cancer and Alzheimer's disease.

Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Recombinant Human USP14 (E.coli, N-6His)

USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1.

Recombinant Human EpCAM/Trop-1 (Mammalian, C-Fc)

Epithelial Cell Adhesion Molecule (EpCAM) is a signal type I transmembrane glycoprotein. EpCAM plays a role in embryonic stem cells proliferation and differentiation; it up-regulates the expression of FABP5, MYC and Cyclin A and Cyclin E. It is highly and selectively expressed by undifferentiated embryonic stem cells.
