CCAs are composed of a hepatic clearance directing moiety which directs the biodistribution of a CCA-containing construct to hepatic clearance; and a binding moiety which mediates binding of the CCA to a compound for which rapid hepatic clearance is desired. Methods to purify the neurotoxin as well as uses thereof are also disclosed.
