The table below shows the number of cells that are singly and doubly stained and in brackets the percentage of cells co-expressing both forms of WT PCSK9 or WT and Q152H PCSK9 from five different views. Immunocytochemistry was carried out by sequential double staining protocol as described at http://www.ihcworld.com/_protocols/general_IHC/immunofl_double_squential.htm
