I have also been using gel for 2 years- any odd reactions bring me right back to immucor cells, tube and PEG if I suspect an alloantibody. David Saikin, I am so sorry I can't make your lecture on gel that you are giving at the Fall Seminar, Northeast Conference. People from my lab will be there, hope to meet you on Thursday at the Blood Bank Rountable discussion. Babs in the lab in Bridgton Maine
