sdAb anti-TagFP

Fluorescent proteins (FPs), widely used as protein tags in cell biology and microscopy, have revolutionized protein imaging and biochemical applications. TagRFP, a monomeric red fluorescent protein, was engineered from TurboRFP (derived from Entacmaea quadricolor) to exhibit an extended fluorescence lifetime and enhanced photostability (Merzlyak et al., 2007). Through further mutagenesis, this red-emitting protein was transformed into the blue-emitting TagBFP (Subach et al., 2008). A few years later, an improved version known as mTagBFP2 was introduced, offering greater brightness and stability (Subach et al., 2011). In 2007, mKate was developed from TagRFP, noted for its excellent far-red fluorescence and photostability (Shcherbo et al., 2007). The most currently available variants can be found on an open-source Fluorescent Protein Database FPbase.

sdAb anti-TagFP binds strongly to TagRFP, TagRFP657, TagBFP, mTagBFP2, mKate and mKate2. For detailed information, please refer to our FP Specificity Chart.
