*If there is '''insufficient tissue''' left for immunohistochemistry after standard (usually H&E) staining, you can potentially ask a histotechnologist to destain a glass slide and subsequently perform IHC on that slide. | |||
*Look for a specified '''panel''' for the presentation at hand. For example, for an undifferentiated tumor with no clear lineage differentiation, an initial panel of cytokeratin (CK), S100, vimentin and LCA (CD45) can be used.<ref name="pmid25427040">{{cite journal| author=Lin F, Liu H| title=Immunohistochemistry in undifferentiated neoplasm/tumor of uncertain origin. | journal=Arch Pathol Lab Med | year= 2014 | volume= 138 | issue= 12 | pages= 1583-610 | pmid=25427040 | doi=10.5858/arpa.2014-0061-RA | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25427040 }} </ref> | *Look for a specified '''panel''' for the presentation at hand.
