■ 質(zhì)粒簡(jiǎn)介
ptdTomato-N1 is a mammalian expression vector designed to express a protein of interest fused to the N-terminus of tdTomato. td Tomato is a member of the family of fruit fluorescent proteins (1) derived from the Discosoma sp. red fluorescent protein, DsRed (2). Because the Tomato protein has a tendency to dimerize, the vector was designed with two copies of the Tomato coding region linked together to allow intramolecular dimerization. As a result, each tdTomato RNA transcript encodes a tandem dimer of the Tomato protein (excitation and emission maxima equal 554nm and 581nm, respectively). Expression of td Tomato as a tandem dimer prevents the fused protein of interest from being forced into a dimeric complex. Fusions that retain the fluorescence properties of tdTomato can be monitored by flow cytometry and localized by fluorescence microscopy. The multiple cloning site (MCS) in ptdTomato-N1 is positioned upstream of the tdTomato coding sequence. A Kozak consensus sequence, located between the MCS and the tdTomato coding sequence, enhances translational efficiency of the unfused tdTomato protein in eukaryotic cells (3). SV40 polyadenylation signals downstream of the tdTomato coding sequence direct proper processing of the 3' end of the tdTomato (or fusion gene) mRNA.
