Cell-free assay product and method of use thereof for measuring activity of frizzled receptors
Patent 8119354 Issued on February 21, 2012. Estimated Expiration Date: October 9, 2028. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
The present invention relates to cell free assays for measuring receptor activity, especially for measuring a constitutive or a non-constitutive activity of frizzled re-ceptors and uses thereof. The present invention further concerns a method for measuring a constitutive or non-constitutive activity of a frizzled receptor and a method for obtaining an active frizzled receptor ligand.
