Abstract/OtherAbstract:
A human hepatoma cell line (HepG-2) was probed for the presence of lecithin: cholesterol acyltransferase (LCAT) using an antiserum to human plasma LCAT. Double immunodiffusion analysis using antiserum to human plasma LCAT revealed a single precipitin line in the sonicated cell homogenate. This precipitin line showed a reaction of identity with highly purified plasma LCAT. The presence of LCAT within the hepatoma cells was also confirmed by an immunofluorescence test. In contrast, the cell culture supernate showed a weak and inconsistent precipitin line. These data suggest that HepG-2 cells synthesize LCAT but secretion of the enzyme by these cells into the culture medium may be partially or totally impaired.
