Staining with clone MCD1 monoclonal antibody is illustrated by flow cytometry analysis of a sample of Molt4 cells. Direct staining was performed using 10 microl of the FITC-conjugated antibody with 100 microl cell suspension. The antibody was tested by flow cytometry using a lyse-wash method. Obtained data support the premise that these reagents are equivalent in their reactivity with Molt4 cells. Values are expressed in terms of % of the total count: Product code: AM39006FC-N Mean % positive: 97, 79 S.D.: 0.82 % CV: 0.84
