Sorry for the late reply. Actually I learned the method from a refence,but I
could not remember the exact journal and article now.
The sections I used were acetone-methanol(1:1) fixed paraffin embedded
sections with. I have not tried on formalin-fixed paraffin-embedded
sections.But I remember that in the reference mentioned above,it reads that
this method is applicable on formalin-fixed sections.
The procedures are not special,just add the pretreatment with 88% formic
acid.That is to say,
Draw a circle around the sections with PAP pen;
Incubate with PBS;
Incubate with 88% formic acid (diluted with ddH2O i.e. pure water) for 20
minutes in room temperature;
Incubate with 10% fetal bovine serum as the blocker (or other kinds of block
Incubate with monoclonal mouse anti-C4d antibody (A213 from Quidel USA) at
Incubate with FITC-conjugated rabbit anti-mouse IgG antibody (from DAKO) for
40 mins at RT;
Observe under fluorescent microscope...
Besides, it is not any advertisement for those products I mentioned! :-)
Just a little experience.
Wish it is helpful. And thank you for your attention.You are much welcomed!
