Re: haemoglobin staining
Interestingly, 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).

demonstration of haemoglobin
