There has recently been a proliferation of commercial kits available for
apoproteins A-I and B. Since reference procedures for apoproteins have not
yet been established we have elected to compare apoprotein kit methods with
highly standardized apoprotein B and A-I radioimmunoassays developed at the
Northwest Lipid Research Center. Commercial radial immunodiffusion kits for
apoproteins A-I and B were obtained from three separate companies,
Calbiochem, Daiichi Pure Chemicals, and Tago, and a commercial
radioimmunoassay kit for apoprotein A-I was obtained from Ventrex
Laboratories. Considerable differences were observed between the commercial
kit methods and the Northwest Lipid Research radioimmunoassay methods. Some
of the differences between methods were related to the assigned value of
the reference materials. Other differences between methods were clearly
method-dependent.
