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.


Fluorophore and Reagent Selection Guide for Flow Cytometry

The Fluorophore and Reagent Selection Guide poster in the center of BioProbes 75 highlights the recommended fluorescent dyes and fluorescent proteins for six different excitation lasers, as well as their common emission filters and Attune NxT channel. Also included for each laser are dyes for viability, DNA content/cell cycle, cell proliferation, apoptosis, reactive oxygen species, and phagocytosis assays. Use this poster to choose the best reagents for your next flow cytometry experiment.
