Arno's post in Ficin vs Papain was marked as the answerJust to bring an update on this topic which did not generate much fervor :-)) this was discussed at AABB and it seems at the time Ficin was found more stable than papain... but no other reasons were brought forward. Was there an easier access to fig trees at the time may be?

Arno's post in What does Lui stand for? (Freeze-thaw elution) was marked as the answerIn this paper from 1985, "The Lui elution technique A simple and efficient method for eluting ABO antibodies c. s. FENG, K. c. KIRKLEY, c. A. EICHER, AND D. s. DE JONGH, TRANSFUSION 1985; 25:433-434.", the authors thank A. Lui. MT(ASCP)SBB, who introduced this technique to them. Therefore, I believe Lui is the name of the MT who invented this elution method.

Arno's post in A 10month A pos baby with anti- A was marked as the answerHere is an interesting paper showing that antibodies to red cell/platelet... may be transmitted via breast milk indeed, causing prolonged HDFN. Milk contains mostly IgA but IgM and IgG may be present of course and IgGs can cross the different barriers up to blood circulation (not on the same model - not actively - as the placenta though). The surprizing part here is the mother and baby are group A, A antigen is ubiquitous so the anti-A titer in breast milk should high enough to interfer with reverse group despite the adsorption of anti-A on various tissues.
