TABLE 1.

Lipid levels and apo(a) isoform sizes of plasma samples

Sample Identification	Lp(a) (mg/dl)	Apo(a) Isoform Size	HDL (mM)	LDL (mM)
151	109	19	1.91	1.7
172	158	20, 19	1.36	2.3
228	109	22, 18	1.44	5.3
229	122	17	1.72	2.2
230	89	19	1.36	2.7

Lp(a) levels were measured by immunoassay [QUANTIA Lp(a), Abbott Diagnostics, Abbott Park, IL]. Lipid levels were determined by enzymatic assay (Roche). The apo(a) isoform size was determined by electrophoresis on 4% polyacrylamide gels followed by immunoblotting (42) and is given as the number of KIV₂ repeats relative to apo(a) isoform standards.
