Clone KK3 has been developed and validated specifically for the immunohistochemical (IHC) detection of CD73 in routine fixed human tissue specimen (FFPE). The CD73-adenosine axis has emerged as one of the most promising therapeutic targets in immuno-oncology. An immunosuppressive role of CD73-adenosine in cancer has been demonstrated by several labs independently. Immunohistochemical (IHC) application of monoclonal antibody KK3 may help to develop a better understanding of cell- and tissue- specific roles of CD73. Moreover, it will be important to differentiate patient populations for adenosine-targeting agents. Immunohistochemical (IHC) application of anti-CD73 clone KK3 may provide valuable information for identification of patients that will benefit from novel therapies.
