FIX&PERM Cell Fixation and Permeabilization Kit

Flow cytometric analyses with monoclonal antibodies were so far mainly restricted to cell surface molecules. Intracellular structures such as cytoplasmic or nuclear enzymes, oncoproteins, cytokines, immunoglobulins etc. were largely excluded from such studies. Also excluded from flow cytometric studies were cytoplasmic localizations of well-established membrane molecules like CD3 and CD22, which, in their cytoplasmic form, are the most reliable lineage markers in undifferentiated leukemia. With the FIX&PERM® Kit flow cytometric analysis of intracellular antigens has become as easy as surface antigen studies. The only prerequisite is the availability of suitable antibody conjugates. Most of the available monoclonal antibody conjugates can be used with the FIX&PERM® Kit, some determinants are sensitive, however, to the fixation step involved. This and the optimal fixation time have to be tested for each reagent.

CD15-FITC is a monoclonal antibody (MAb) labelled with fluorescein isothiocyanate (FITC) designed for use as a direct immunofluorescence reagent in the identification and enumeration of cells which express the CD15 antigen by flow cytometry. The CD15 MAb is applied for the initial evaluation of acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) together with a panel of other antibodies. Interpretation of results must be made within the context of the patient?s clinical history and other diagnostic tests by a certified professional.


Provided as 0.2µm sterile filtered solution in phosphate buffered saline with 0.08% sodium azide.
