Vector description

Gateway® TagBFP-AS-C 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 3'-end of TagBFP gene allows to generate fusions to the TagBFP C-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 E. coli.

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 C-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-C with a destination vector containing this gene in a correct reading frame. In this case, the protein of interest will be expressed as a fusion to the TagBFP N-terminus.

TagBFP-tagged fusions retain fluorescent properties of the native protein allowing fusion localization in vivo.

Note: The plasmid DNA was isolated from dam+-methylated E. coli. Therefore some restriction sites are blocked by methylation. If you wish to digest the vector using such sites you will need to transform the vector into a dam- host and make fresh DNA.

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-C
  - 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 E. coli host and growth media for expression
  - Appropriate selective plates.

Propagation in E. coli

Suitable host strains for propagation in E. coli include DH5alpha, HB101, XL1-Blue, and other general purpose strains. Plasmid incompatibility group is pMB1/ColE1. The vector confers resistance to kanamycin (30 μg/ml) to E. coli hosts. Copy number in E. coli is about 500.
