Even low levels of pre-formed alloantibodies to HLA class II antigens represent a risk of rejection. We present here a method for blocking non-specific flow crossmatch reactions using pooled, heat-inactivated rabbit serum. This method shows very low background and minimal non-specific reactions. In addition, it avoids the use pronase enzyme that can non-specifically digest different cell surface proteins. %U http://www.sjkdt.org/article.asp?issn=1319-2442;year=2009;volume=20;issue=4;spage=662;epage=665;aulast=Hajeer
