Put as little as 20 ul of solution in dot on parafilm. Put coverslip down on solution. To remove coverslip without ripping tissue/cells, touch pipette tip with buffer at edge of coverslip just slightly lifting and inject buffer slowly (100 ul tip) so coverslip floats. Grab edge with tweezrs and gently pull off to the side.

If not I would recommend using parafilm as a coverslip and using the diluted antibody on the entire slide. I found that 100 uL was sufficient to stain my sample without evaporating when incubated at 4C in a humid chamber overnight. If you are using multiple antibodies from the same host on one slide I would recommend using as little buffer as completely covers the section. I find that if I use 100 uL in a small space that would be sufficiently filled with 50 uL then the buffer will creep over the PAP pen when it contains triton.

Although they are made for plating live cells they might be useful for your application. They are a borosilicate glass cylinder similar to a cloning ring having an optically flat polished end better than 1/4 wave that hydrostatically seals to another flat optical surface like a slide. It is used when plating cells to position them for observation and improving plating time by restricting the amount of media that the cells have to re-equilibrate after being tripsinized. They are easily removed after processing with a forcep and leave no residue. Culture cylinders are reusable and autoclaveable. Let me know if you want to try one. Free samples have a 6 or 8mm ID. If it works for your application you can get any size you want.

I used exactly the method Virginia described for years with excellent results. A PAP pen is okay, but in my experience was less effective when using buffers containing detergent, and is *really* expensive. I have also used glass coverslips with similar efficacy, you just have to be more careful when removing them; I used a large bath of buffer and submerged the whole slide so that the coverslip floated off quickly and smoothly without pulling the tissue off the slide. As a disclaimer, this was done on cryosections, not paraffin-embedded tissue. You also cannot recover the antibody solution if you use this coverslip method. Best of luck!

I have had occasions where people have used too much and then when they mount their sections (with aqueous mount), the mountant sits in a bubble, which causes an issue if the lens has a short working distance. Sometimes, I will advise them to remove the wax carefully (and safely!) by using xylene.

We are doing IHC with dewaxed tissue sections on slides. When we incubated the tissue sections with antibodies, esp o/n at 4C, the antibody solution (with 0.1% triton) did not stay inside the circle we drew with a diamond scribe or sharpie; it spread over the slide, sometimes the sections dried. I wonder if any of you have an easy and simple way with little effort/cost to prevent solution running off the slides. Any input is highly appreciated.

Incubate samples with antibodies in the cutout well, then remove the mask before mounting with a coverslip.

When you are finished, the PDMS can be gently removed with a tweezer.

We would then place this in a humidity chamber (petri dish affixed with moist towels secured with nail polish on the inside cover and on the bottom). The slides would be placed on two wooden applicators (so it is not touching the moist towel) and we would incubate without solution drying out. Too rinse simply flood the slide with PBS, then remove the floating c/s horizontally.

Make sure you cut the piece of Parafilm narrower than the slide, so that the antibody solution does not run down the sides into the filer paper or whatever the slide is sitting on. Also, do not overlap with the frosted, writing area on the end of the slide, if there is one - the capillary action would wick the solution away from under the Parafilm. Here is a plug for my book chapter -Fig. 2N shows the Parafilm use: Vitha, S. and Osteryoung, K. W. (2011) Immunofluorescence Microscopy for Localization of Arabidopsis Chloroplast Proteins.
