Subject: Re: haemoglobin stainingInterestingly, some years ago, I was trying to prove that marks on the breast of a murdered woman were in fact bite marks, I found all the non bendizene methods for haemoglobin trhat may be found in the standard text-books were inconclusive.The benzidine method successfully demonstrated the igment, confirming the strong clinical and circumstantial evidence.I drew the conclusion that, despite strong the proven carcinogenicity of this substance, it may on occasions be the most reliable histochemical method of demonstrating haemoglobin in human tissue.It is a prohibited substance in the UK and that may mean I was law breaking in carrying out the investigation(the suspect was found guillty).See.The use of benzidine for the histological demonstration of haemoglobin in human bite marks.
