We store blocks and slides "forever". We have paraffin blocks from before 1930. "Room temperature" in Norway is usually about 20 degrees Celcius. Some stained slides will fade with time (silver techniques, immuno), but the routine HE usually last for many, many years. After we excanged Xylene with a substitute (Tissue-Clear) four years ago, we had some "bleeding" and fading of the HE-stains, but after taking more care changing the Xylene substitute in the clearing step more often this is no more a problem. The paraffin blocks keep very well. We frequently do section and stain as well as do molecular techniques (PCR, In situ) on material from the 1970'ies and before, and it's remarkable how well the formalin fixed, paraffin embedded tissue keep. I would not keep the blocks in a fridge, as you say, the humidity in the fridge is quite high. The time to cool a block from room temperature to suitable for sectioning is only about two minutes. Now, because Norway has a relatively cold climate, the air humidity is also quite low compared to warmer climates, even if it rains here ALL the time... ;-) Heat and high humidity might affect your blocks.

It is assumed that the room is air conditioned, otherwise if the temp is above 80?F some blocks may stick together, although that is not a real problem. If at 4?C you will need a refrigerated room or a series of refrigerators, which is an additional and unnecessary expenditure. We use to store the blocks for 9 years, unless it is a special case (used in teaching) and those are stored forever. Supposedly you use the slides for some procedure and those cut as "extras" are kept along with the originals stained in the same files. If you are referring to sections for IHC or other procedure, the epitopes will be oxidized by the oxygen in the air in less than 2 weeks, so they can either be stored in a fridge, or covered with melted paraffin, or stored in mineral oil.

It is purported to be a universal antigen retrieval solution that can be used at lower temperatures (65-70 C for cytoplasmic antigens, and 75-80 C for nuclear antigens): http://innvx.com/unitrievepage.html The company claims that the reagent is a universal retrieval solution for all antibodies and tissues (which is silly of course - how could they know?). Does anyone have any experience with the product? I am interested because I see that increased heat during antigen retrieval causes greater tissue autofluorescence during immunofluorescence stainings. My current protocol is to use 20 minutes at 90-95 C on a hot plate using sodium citrate buffer. Does anyone else either Uni-trieve or a different reagent/protocol for immunofluorescence stainings?
