โœฆ Synopsis


Dryplates

The microheterogeneity of apolipoprotein D was examined by a procedure involving, in sequences: (i) electrophoresis in an immobilized pH 4-7 gradient in an Immobiline DryPlate-polyacrylamide gel supplemented with Ampholine pH 5-7, (ii) covering of the gel with sodium dodecyl sulfate-containing agarose, (iii) electroblotting onto a polyvinylidene difluoride membrane and (iv) immunological identification. Seven isoforms were obtained with partially purified apolipoprotein D. Using this technique the apparent plvalues at 15ยฐC for the isoforms were 4.57,4.67,4.78,4.83 and5.95,6.06and6.19(SDfO.O5forall).Direct stainingofthe Immobiline DryPlate could not reveal the isoforms of partially purified apolipoprotein D.
