FluoTag®-X2 anti-mEos

Cat No: N3102 Category:

375,00 

FluoTag®-X2 anti-mEOS is derived from an in-house developed single-domain antibody (sdAb) that recognizes mEOS, which is a bright monomeric green photoswitchable fluorescent protein derived from Lobophyllia hemprichii.

In 2004 Wiedernmann and colleagues described an engineered fluorescent protein with photoswitchable properties, EosFP, which could be selectively shifted from green to red emission and was derived from a fluorescent protein discovered in Lobopyllia hemprichii. The same study also describes a monomeric, improved version, mEOS. Over the last years, several enhanced versions have been discovered expanding the repertoire of photoswitchable fluorescent probes. An open-source database with the most currently available variants can be found in the fluorescence protein database “fpbase”

Our nanobody binds specifically and strongly to mEOS2, 3.2 & 4b; likely, it also binds other EOS fluorescent proteins. Have a 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.

Shipping: Ambient temperature
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:

This Product is not recommended to be used to detect proteins in Western Blott, sdAbs tend to recognize native/folded protein mainly.

Look at detailed protocols and our specificity chart in our Resource Section.
