tdTomato Nanoselector Magnetic beads

Product Performance

The tandem dimer Tomato (tdTomato) is a genetically improved version of Discosoma sp. fluorescent protein (dsRed). tdTomato is an extremely bright red fluorescent protein, being one of the brightest red-shifted fluorescent proteins available and six times brighter than eGFP. One of the main advantages of fluorescent proteins is that they do not require substrates or reagents for detection, however most of them do need oxygen for the formation of their chromophores. Besides, fluorescent proteins can be measured without lysing cells, whereas this is difficult for luciferases. One of the biggest disadvantages of fluorescent reporters is that they need to overcome cellular autofluorescence. However, in general cellular autofluorescence is lower for the emission wavelength of the red channel, favoring a red fluorescent protein such as tdTomato. For biochemical analysis including mass spectrometry and enzyme activity measurements these tdTomato-fusion proteins and their interacting factors need to be isolated fast and efficiently by immunoprecipitation using the tdTomato Nanoselector Magnetic beads. Due to the single-chain nature of sdAbs and their stable and covalent attachment, no leakage of light and heavy chains is observed during elution with SDS sample buffer.
