I recently came across the web site of a company that provides slides with sections of a wide variety of animal tissues - normal, pathological, transgenic etc: single and multiple tissues, as mounted paraffin sections. The associated photos indicate high quality fixation and sectioning. There are frequent Histonet enquiries about sources of negative and positive controls for immunohistochemistry, special stains etc. This might be such a source. The address is http://www.histobest.com John Kiernan Department of Anatomy & Cell Biology University of Western Ontario London, Canada. = = = _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
