Molecular techniques are now being widely applied in clinical pathology laboratories, yet many people working in these facilities have only limited experience of such procedures. This work, together with Volume I, brings together a broad spectrum of protocols relevant to the routine molecular analysis of pathological samples. Volume I featured those methods which relate to morphological analysis, such as immunocytochemistry, in situ hybridization, chromosome analysis and flow cytometry. This second volume demonstrates additional applications of molecular techniques to clinical samples, including the use of PCR, DNA sequencing and nucleic acid hybridization for such diverse purposes as pathogen identification and forensic studies. For all the protocols, guidance and instructions are given on how to ensure accuracy and reliability, which should appeal to people working at all levels in apthology. The two volumes are also available as a set.
