These pens are designed to produce coherent high quality immunocytochemical preparations more effectively, accurately and with much less waste. They have applications for frozen paraffin and cytological preparations.
As well, they prevent frozen sections and paraffin sections from moving, wrinkling, or falling off the slide during immunostaining procedures.
Warning: Cap tightly when not in use!!!
Processing: Each membrane which is applied by the pen should be allowed to dry completely (approximately 5 minutes) at room temperature prior to routine processing.
Do not use the pens below room temperature. This can cause background staining in immune reaction procedures.
