Vector description

Gateway® TagRFP-AS-N entry clone is a vector containing red (orange) fluorescent protein TagRFP gene variant with codon usage optimized for high expression in Arabidopsis and Saccharomyces. TagRFP 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 TagRFP gene into a number of Gateway® destination vectors for expression in different experimental systems. Multiple cloning site (MCS) located at the 5'-end of TagRFP gene allows to generate fusions to the TagRFP N-terminus for expression, localization and cellular dynamics studies.

To increase mRNA translation efficiency, Kozak consensus translation initiation site is generated upstream of TagRFP coding sequence [Kozak, 1987].

The vector backbone contains pUC origin of replication and kanamycin resistance gene (Kan^r) for propagation and selection in E. coli.

Generation of TagRFP-tagged fusions

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 TagRFP N-terminus when inserted in the same reading frame as TagRFP and no in-frame stop codons are present.

Alternatively, TagRFP gene can be fused to the 3'-end of a gene of interest by LR recombination of the Gateway® TagRFP-AS-N with a destination vector containing this gene in a correct reading frame.

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

LR site-specific recombination

Please refer to Invitrogen Gateway® Technology description for detailed instructions regarding LR site-specific recombination reaction. In general, to transfer TagRFP gene or TagRFP-fusion construct into the destination vector you will need:

  - Purified plasmid DNA of Gateway® TagRFP-AS-N
  - A destination vector of choice
  - Invitrogen LR Clonase^TM II enzyme mix (Invitrogen Cat.# 11791-020)
  - Proteinase K solution (supplied with the LR Clonase^TM 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.
