FluoTag®-Q anti-TagFP is derived from an in-house developed single-domain antibody (sdAb) that recognizes fluorescent proteins deriving from Entacmaea quadricolor, such as mTagBFP, mTagRFP, mTagRFP657, and mKate with high affinity and specificity.
TagRFP was engineered in 2007 from TurboRFP (derived from Entacmaea quadricolor). Tag RFP displayed an extended fluorescence lifetime and showed robust photostability. In 2008 after further mutagenesis and the exchange of ~12 amino acid residues, this red-emitting protein turned into a blue-emitting protein TagBFP. Only several years later, in 2011 a monomeric version of TagBFP was described: mTagBFP2. Today more than 800 entries of various fluorescent proteins can be found in an open-source database with the most currently available variants in the fluorescence protein database “fpbase”
Our sdAb binds strongly to TagRFP, Tag BFP, and mTagBFP2. Look at our specificity chart in our Resource Section.
FluoTags® can be equipped with a single fluorophore for more quantitative readouts (FluoTag-Q), with two fluorophores per single-domain antibody (FluoTag-X2), and we also developed a blend of two sdAbs bindings simultaneously the target proteins and each bearing two fluorophores (FluoTag-X4). For more detailed information on the FluoTags, please check our Technology Section.

Formulation: | A single sdAb clone was lyophilized from PBS pH 7.4 containing 2% BSA (US-Origin). Reconstitute with 200 µL of 50 % glycerol in deionized water. We recommend including 0.1 % sodium azide as a preservative if applicable. When reconstituted in 200 µl, the concentration of single-domain antibody is 5 µM | ||||||||||||||||||

Storing: | Vials containing lyophilized protein can be stored at 4 °C for 6 months. We recommend reconstituting the protein with 50 % sterile glycerol including 0.1 % sodium azide as preservative if applicable. Minimize the number of freeze-thaw cycles by aliquoting the reconstituted protein. Long term storage at -80 °C for up to 6 months. Working aliquots can be stored at -20 °C for up to 4 weeks. We do not recommend storing the reconstituted protein at 4 °C. | ||||||||||||||||||
Protocols: |
Western Blotting is not recommended with this product, sdAbs tend to recognize native protein conformation only. Look at detailed protocols and our specificity chart in our Resource Section.
