|Species Reactivity: Human|
|Fixation: Formalin fixed paraffin sections or acetone-fixed, frozen sections as well as cell smears.|
|Positive Control: Tonsil, thymus, stomach, small intestine, colon, skin, oral mucosa and breast carcinoma, bone marrow, testis, and uterus.|
|Negative Control: Omit primary antibody, isotype control, absorption control|
|Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary|
