Fish her2/neu paraffin block
WebFluorescence in situ hybridization with labeled DNA probes to the pericentromeric region of chromosome 17 and to the HER2 locus can be used to determine if a patient's breast cancer has HER2 gene amplification. Immunohistochemical analysis is used to determine if a tumor exhibits HER2 overexpression. ... Client provided paraffin blocks and ... WebOne HER2-positive case based on IHC (case #16) was HER2-positive based on FISH in the control but HER2-negative based on FISH in the SD samples. No clinically relevant changes (ie, HER2-positive to HER2-negative or vice versa) were identified for HER2 copy number or HER2/CEP17 in the other cases (Fig. (Fig.6 6 ).
