More than 80% of circulating LPL in pre-heparin plasma was found in RLP as RLP-LPL complex.
RLP-LPL complex isolated from pre- and post-heparin plasma was LPL dimers but inactive form.
When THL added in the post-heparin plasma, most LPL dimers were found specifically in the RLP.
Active and inactive form of LPL dimers were found in non-RLP and RLP in post-heparin plasma.
