I want to dissect visual cortex tissue for quantitative RT-PCR and I found that it is difficult for me to get visual cortex tissue evenly from diffrent mice. Does anyone have any suggestion? Any advice is welcome. Thanks a lot.
Hello, you may use a tissue punch of appropriate size rather than microscissors or dumont forceps. This should lead to quite reproducible results.Usally these biopsy devices are used by dermatologists.They are inexpensive and ususally for single-use.
Dear Genius, thanks a lot for your nice answer. It sounds interesting. I have't seen this device. Would you like to give me some citation? I find a paper about this (Effects of soft tissue punch size on the healing of peri-implant tissue in flapless implant surgery. PMID: 19926500), but I am not sure whether it is right.
