Abstract:
The present invention includes a PCSK9 activity inhibition assay system, kits, compositions and methods. The present invention includes a cell having a first vector capable of expressing a catalytic fragment of PCSK9, a second vector capable of expressing a prodomain of PCSK9 and a V5 protein with a detectable label. The V5 protein forms a fusion protein with the prodomain of PCSK9 and wherein cleavage of the prodomain by the catalytic fragment of PCSK9 releases a detectable signal.
