Recent studies of circulating lipoproteins in man and the rat have shown that apolipoprotein B in plasma exists in two immunologically distinct forms with apparent Mr, in the rat, of approximately 335,000 (apoB335K) and 240,000 (apoB240K). With isolated, perfused organs and single and double isotope... View More
