Amplify signals for fluorescence imaging: SuperBoost Kits with Alexa Fluor tyramides for signal amplification

Many functionally important proteins such as transcription factors and cell-surface cytokine receptors have native expression levels far below the detection threshold of labeled primary and secondary antibodies. The Invitrogen SuperBoost kits with Alexa Fluor tyramides provide a highly sensitive method for detecting low-abundance targets in immunocytochemistry (ICC), immunohistochemistry (IHC), and in situ hybridization (ISH) applications. Tyramide SuperBoost technology combines the brightness of Alexa Fluor dyes with poly-HRP–mediated tyramide signal amplification to discern signal from noise, yielding precision and sensitivity 10–200 times greater than that of standard ICC/IHC/ISH methods and 2–10 times greater than that of other tyramide amplification techniques, including traditional TSA™ methods.
