- Description of Target:
- Chylomicron remnants and very low density lipoprotein (VLDL) remnants are rapidly removed from the circulation by receptor-mediated endocytosis in the liver. Apolipoprotein E, a main apoprotein of the chylomicron, binds to a specific receptor on liver cells and peripheral cells. ApoE is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. Defects in apolipoprotein E result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants.Chylomicron remnants and very low density lipoprotein (VLDL) remnants are rapidly removed from the circulation by receptor-mediated endocytosis in the liver. Apolipoprotein E, a main apoprotein of the chylomicron, binds to a specific receptor on liver cells and peripheral cells. ApoE is essential for the normal catabolism of triglyceride-rich lipoprotein constituents. The APOE gene is mapped to chromosome 19 in a cluster with APOC1 and APOC2. Defects in apolipoprotein E result in familial dysbetalipoproteinemia, or type III hyperlipoproteinemia (HLP III), in which increased plasma cholesterol and triglycerides are the consequence of impaired clearance of chylomicron and VLDL remnants.

PRETREATMENTS WITH CITRATE SOLUTION
FOR WATER BATH
1) Fill water bath with warm water, set it for 85oC.
2) Put square glass jar (filled with the citrate solution) on a rack in the water bath, so it gets heated to the appropriate temperature, i.e., 85oC.
3) Put a tissue rack with the to be treated tissue in the water bath for 30 minutes.
4) Take it out and let it cool down in either citrate or phosphate buffer.
1) Put plastic tray filled with some water (about 3 cm high) in microwave.
2) Put glass tray with citrate buffer, with rack (new rack) with sections in glass tray.
3) Heat for 3 min at 440 Watt setting.
4) Let it cool down (20 min) and rinse in buffer.
0.05 M NaCitrate solution; add 14.7 g of NaCitrate-2 hydrate to 1 liter of dH2O,
NOTE: adjust pH. to pH 6.0
1. Pretreat tissue in hot citrate solution (see protocol).
2. Use small (4 x 6) tray; rinse tissue 3 X 5 min each in TBS-T (Tris Buffered Saline + 0.5% Triton; pH 7.6). Approximately 20 ml/tray.
