Description

The loxP-PGK-gb2-neo-loxP template is designed to allow neomycin/kanamycin selection in prokaryotic and eukaryotic cells. The loxP-PGK-gb2-neo-loxP template encodes the neomycin/kanamycin resistance gene which combines a prokaryotic promoter (gb2) for expression of kanamycin resistance in E.coli with a eukaryotic promoter (PGK) for expression of neomycin resistance in mammalian cells. The prokaryotic promoter gb2 is a slightly modified version of the Em7 promoter. It mediates higher transcription efficiency than the normally used Tn5 promoter. The promoter of the mouse Phosphoglucokinase gene (PGK) is used as eukaryotic promoter. A synthetic polyadenylation signal terminates the kanamycin/neomycin expression. The cassette is flanked by loxP sites for later excision by Cre-recombinase. Using the provided PCR template one can easily create a loxP-PGK-gb2-neo-loxP cassette flanked by any restriction sites to clone the cassette into the vector of choice. The restriction sites can be introduced by adding the corresponding sequence in the PCR primer. The template can easily be used to generate targeting constructs mediated by a single Red/ET Recombination step. The loxP-PGK-gb2-neo-loxP template is not linear but plasmid based (3446bp in size). Due to its R6K origin it can not replicate in most E.coli strains. The PCR product can therefore be used directly for downstream applications without any further purification. At least 20 PCR reactions can be performed using 1ul per reaction as template.
