Overview
Monoclonal antibody 17D5 reacts with human CD33. In initial testing—on lysates of HEK293 cells that overexpressed myc-tagged human CD33 isoforms—it detected all three isoforms on Western blots and immunoprecipitated each isoform. The antibody was also shown to work in immunocytochemical applications, staining CD33-transfected HEK cells.
Monoclonal antibody 17D5 recognizes human CD33 overexpressed in HEK cells. A) Western blots of lysates of HEK293 cells transfected with myc-tagged human CD33 isoforms or empty vector (mock); blot probed with 17D5. Note that 17D5 recognizes all three isoforms of human CD33. B) Left blot, lysates immunoprecipitated with 17D5. Right blot, cell lysates (input for immunoprecipitation). Blots probed with anti-myc antibody 9E10. All three CD33 isoforms are captured by 17D5. *, non-specific bands. [Courtesy of Christian Haass' laboratory.]
Monoclonal antibody 17D5 recognizes human CD33 over expressed in HEK cells. HEK cells transfected with human CD33 (CD33-3 or CD33m) or mouse (CD33-m) isoforms were fixed, permeabilized, then incubated with 17D5 followed by a fluorescently conjugated secondary antibody. Cultures were counterstained with the nuclear stain DAPI (blue). Note 17D5 immunoreactivity (magenta) in the human CD33-transfected cells. As expected, this antibody did not recognize mouse CD33.

Generation and epitope mapping
This antibody was generated in rats immunized with a peptide in the C-terminal region of human CD33 that is present in all three isoforms, coupled to ovalbumin. Epitope mapping has not been reported.
Specificity
Clone 17D5 reacts with all three isoforms of the human protein. The antibody is not expected to react with mouse CD33.
Validation
No data.
