Forensic Body Fluid Identification by Analysis of Multiple RNA Markers Using NanoString Technology
This paper describes the detection of human HbA and human HbF antigens in bloodstains by an antibody-absorption test. In the test, antisera to human HbA or HbF were absorbed with biological stains, then the antibodies with decreased capacities for agglutination were titrated by a microtiter technique using latex particles coated with the corresponding antigens. This test was proved to be specific, sensitive and reproducible. The indicator latex particles coated with human HbA or HbF could be stored at -70 degrees C for over 10 years.
