Anti-HLA class I (HLA-A,B,C) antibody


Immune checkpoint inhibitors and cancer vaccines are currently attracting a lot of attention as novel cancer treatment strategies. In order to achieve sufficient anti-tumor effects using these treatments, target tumor cells need to express HLA class I antigens. It is important to evaluate the expression of HLA class I antigens in tumor cells in order to establish treatment methods. This product is an antibody that recognizes human HLA-A,B,C. Because it can be used for immunostaining, it is useful for evaluating the expression of HLA class I in tumor cells and tissues.

Flow cytometry

  • The best clone for immunohistochemistry
  • The product is ready to use

Application data

Immunohistochemistry (fluorescent staining manual method)

HLA class I expression is observed in stromal cells, normal epithelial cells, infiltrating lymphocytes and macrophages. However, it is hardly observed on cancer cells (cytokeratin positive). HLA-DR is expressed on monocytes and macrophages.

Tissue:Head and neck cancer
Orange:HLA class I (Code No. D370-3H)
Red:HLA-DR (clone LN-3)
Blue:Cytokeratin (clone AE1/AE3)
Data was kindly provided by Dr. Susumu Suzuki (Aichi Medical University of Medicine).
