The StreptaClick®-HRP kit optimizes the multiplex TSA workflow, from rapid conjugation to scanning speed. The patented StreptaClick® technology enables the quick conjugation of HRP-antibodies within minutes. Additionally, the quenching buffer accelerates the protocol and also allows for the staining of frozen tissues. The TSA dyes are handpicked to ensure an enhanced signal amplification, to increases image quality and scanning speed. The protocol enables the completion of 7-color TSA multiplex IHC (DAPI + 6 biotinylated antibodies) within a single day. For direct imaging of the 7-plex IHC stainings, we recommend SpectraSplit® 7 filters.
