Gateway® TagBFP-AS-N entry clone is a vector containing blue fluorescent protein TagBFP gene variant with codon usage optimized for high expression in Arabidopsis and Saccharomyces (see reporter description). TagBFP coding sequence is flanked by attL1 and attL2 sites allowing easy site-specific recombination. The Invitrogen Gateway® Technology provides a rapid and highly efficient way to transfer the TagBFP gene into a number of Gateway® destination vectors for expression in different experimental systems. Multiple cloning site (MCS) located at the 5'-end of TagBFP gene allows to generate fusions to the TagBFP N-terminus for expression, localization and cellular dynamics studies.
To increase mRNA translation efficiency, Kozak consensus translation initiation site is generated upstream of the TagBFP coding sequence [Kozak, 1987].
The vector backbone contains pUC origin of replication and kanamycin resistance gene (Kanr) for propagation and selection in
Generation of TagBFP fusion proteins
A localization signal or a gene of interest can be cloned into MCS of the vector both before and after site-specific recombination with a destination vector. It will be expressed as a fusion to the TagBFP N-terminus when inserted in the same reading frame as TagBFP and no in-frame stop codons are present.
Alternatively, TagBFP gene can be fused to the 3'-end of a gene of interest by LR recombination of the Gateway® TagBFP-AS-N with a destination vector containing this gene in a correct reading frame.
TagBFP-tagged fusions retain fluorescent properties of the native protein allowing fusion localization in vivo.
Note: The plasmid DNA was isolated from dam+-methylated
LR site-specific recombination
Please refer to Invitrogen Gateway® Technology description for detailed instructions regarding LR site-specific recombination reaction. In general, to transfer TagBFP gene or TagBFP-fusion construct into the destination vector you will need:
- Purified plasmid DNA of Gateway® TagBFP-AS-N
- A destination vector of choice
- Invitrogen LR ClonaseTM II enzyme mix (Invitrogen Cat.# 11791-020)
- Proteinase K solution (supplied with the LR ClonaseTM II enzyme mix)
- TE-Buffer, pH 8.0 (10 mM Tris-HCl, pH 8.0, 1 mM EDTA)
- Appropriate chemically competent
- Appropriate selective plates.
