Tangential (crossflow) filtration of a plasma/serum mixture through 0.2 micrometer-poresize polycarbonate track-etch membrane filters (PC) at pressures less than 10 psi removes low density lipoproteins (LDL) and very low density lipoproteins (VLDL) but not high density lipoproteins (HDL) from the filtrate. At pressures greater than 10 psi all lipoproteins pass through the PC. Once the filters have been intruded with LDL and VLDL those lipoproteins continue to pass the filters despite subsequent reduction in differential pressure below 10 psi.
在压力小于10磅力/平方英寸的情况下，通过孔径为0.2微米的聚碳酸酯核孔膜过滤器（PC）对血浆/血清混合物进行切向（错流）过滤，可从滤液中去除低密度脂蛋白（LDL）和极低密度脂蛋白（VLDL），但不会去除高密度脂蛋白（HDL）。在压力大于10磅力/平方英寸时，所有脂蛋白都会通过PC。一旦过滤器被LDL和VLDL侵入，尽管随后压差降至10磅力/平方英寸以下，这些脂蛋白仍会继续通过过滤器。
