I am new in this forum and I hope that I will have answers to my request.
My problem concerns the sectioning of a spleen from a mouse. This mouse is naive, does not bear any tumors and whatever the mouse specie spleen.bmp 441.05K 107 downloadsand the protocol to freeze the slpeen are (snap freezing with or without isopentane, with or without liquid nitrogen, slow freezing with dry ice) I always observe freezing artefacts. The spleen is embedded in OCT and immediately frozen. I joined a photo showing the "white clumps" forming in the organ during sectioning, these white clumps turn into holes after sectioning...
I've never dealt with this troubleshooting in the past and I would appreciate to receive help from you as I need to cut urgently some spleen sections for my project.
Thank you for your help

Thanks for your advice, this is a great idea.
I'll try to put some sucrose into the spleen for 24hours before snap freezing the sample.
