A new monoclonal anti-A. Culture supernatants with the performance of hyperimmune human reagents.

By proper selection for good growth and high avidity, we have prepared a new anti-A monoclonal antibody producing cell line that gives culture supernatants as potent as US-licensed commercial hyperimmune human reagents and which meet USA FDA standards without the need for concentration. The production and use of this reagent is cost effective and makes it a candidate to replace conventional anti-A typing reagents.
