Affinity columns containing anti-apolipoprotein A-I or A-II were used to fractionate plasma into subpopulations of lipoprotein particles containing: a) apoA-I [Lp(A-I)]. b) apoA-I and A-II [Lp(A-I with A-II)]. and c) apoA-I but no A-II [Lp(A-I without A-II)]. Single vertical spin and electron microscopy analyses of these HDL subpopulations demonstrated that acid elution from the affin... https://allfixelectricales.shop/product-category/oven-grill-element/
