Dear Histonetters, I am getting ready to purchase an antibody to MUM1 Protein. I noticed that they suggest 1mMEDTA at 9.0ph for antigen retrieval. Has anyone tried Ventana CC1 for antigen retrieval? Any suggestions of dilutions and pretreatments would be appreciated. Elaine Dooley HTL Shands Teaching Hosp. 352-265-0111 ext 72117
