The detection of Rh antigens (D,C,c,E,e) on bloodstains by a micro-elution technique using low ionic strength
Ninety experimental bloodstains, were examined, with the intention of detecting the principal Rh antigens, by using a micro-elution method improved by the use of low ionic strength solution (LISS) and papain-treated red cells. This method makes it possible to employ most commercially produced sera in routine forensic haematology laboratory work. The antigens could regularly be detected in stains of the following ages: D, C and c in stains of at least 6 months, E in stains of at least 4 months, and e in stains of at least 2 months.
