1. Measured by its binding ability in a functional ELISA.
2. Immobilized human RSPO3-His (146) (Cat:11185-H08H1) at 10 μg/mL (100 μL/well) can bind human RNF43-Fc. The EC50 of human RNF43-Fc is 0.01-0.03μg/mL.
A DNA sequence encoding the human RNF43 (NP_060233.3) (Met1-Tyr197) was expressed with the Fc region of human IgG1 at the C-terminus.
Predicted N Terminal
The recombinant human RNF43/Fc comprises 412 amino acids and has a predicted molecular mass of 45.8 kDa. The apparent molecular mass of the protein is approximately 52 kDa in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4.
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -70℃
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.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
RNF43 mutations are frequently detected in colorectal cancer cells and lead to a loss of function of the ubiquitin E3 ligase. The outer mitochondrial membrane 34 (TOMM34) and ring finger protein 43 (RNF43) as highly expressed oncogenes in malignant colorectal tumors. RNF43 is a tumour suppressor gene that suppresses the Wnt-beta-catenin signalling pathway.
