            I would suggest that you deep six the carbowax idea, as when it works it
is fine but often requires a lot of messing around to get the correct condtions for
your tissue. Additionally the sections are difficult to handle.
Would you define which antigens you are trying to demonstrate please  as this makes a
difference in the types of fixation etc. that can be recommended.
