This mouse IgG2b, κ isotype control is a monoclonal antibody, clone 27-35, that is specific for the dansyl (5-[dimethylamino] naphthalene-1-sulfonyl) hapten. The dansyl (DNS) hapten is not expressed on human cells or human cell lines. The 27-35 immunoglobulin was selected as an isotype control following testing that demonstrated low background staining on a variety of mouse and human tissues.
The antibody was conjugated to BD Horizon Red 718, which has been developed exclusively for BD Biosciences as a better alternative to Alexa Fluor® 700. BD Horizon Red 718 can be excited by the red laser (628 – 640 nm) and, with an Em Max around 718 nm, it can be detected using a 730/45 nm filter. Due to similar excitation and emission properties, we do not recommend using R718 in combination with APC-R700 or Alexa Fluor® 700.
