HI,
   ck7 1:50 ( m7018 ) and ck20 1:100 ( m7019 )  this is from DAKO. Target
retrieve them using heat induced epitope retrieval. Then incubate for 30
min. in primary , secondary and tertiary  LSAB+ detection kit from DAKO.
This usually works quite nicely.
    gee does it look like I use DAKO junk occasionally
good luck.
