Lipid extraction from parrafin embedded tissue ? - (Jan/21/2013 )
Hi,
I am planning on doing lipid analysis on cells, tissue (fresh frozen) and parrafin embedded.
Among other things I want to perform a cholesterol level measurement, is it possible to do so by lipid extraction from formalin-fixed parrafin-embedded tissue ? (Fresh frozen is probably the best but I have more material parrafin embedded)
Thank you;

Unfortunately for you, the standard process for paraffin embedding is to dehydrate the tissue first (paraffin is immiscible with water). This is most commonly done in a series of graded alcohols followed by xylene, which will dissolve the fats.
