Immunohistochemical is a term used in medicine and biology to describe a method that combines the use of antibodies and dyes to detect specific proteins or molecules in body tissues.
Full definition
Based on the results of
immunohistochemical analysis, the cells are TdT (+), CD56 (+), CD123 (+) and negative for myeloperoxidase (MPO), CD34, CD117, CD20, CD3 and EBV.
To further confirm the alteration of DDX3 expression in cancer specimens, the expression profiles of DDX3 were examined in normal - tumor paired HCC samples
by immunohistochemical staining analysis using specific anti-DDX3 antibody.

several immunohistochemical predictive biomarkers have been proposed for clear cell RCC including pS6 for temisorimus therapy and CAIX for high dose IL - 2.
While metastatic sites may have originated from the primary tumor, several studies have demonstrated a
different immunohistochemical or mutation profile compared to the primary.
Previous immunohistochemical analysis of both fresh - frozen and / or paraffin embedded tissues showed that PD - L1 was variably expressed by primary and metastatic RCC tumor cells as well as TILs and although Thompson et al report slightly higher rates of PD - L1 expression in metastatic versus primary specimens, a thorough comparison in matched samples has not been made.
