Description:
pGPS2.1 is the Transprimer-2 donor plasmid used in the GPS™-1 Genome Priming System (NEB #E7100S). TnsABC* Transposase removes the Transprimer-2 element from pGPS2.1 and inserts it randomly into the target DNA in vitro (1-3). Transprimer-2 encodes chloramphenicol-resistance. This double-stranded plasmid is 4490 bp in size.
Source:
pGPS2.1 is isolated from E. coli BW23474, an E. coli strain that expresses the pir-116 replication factor (4), by a standard plasmid purification procedure.
Concentration:
20 μg/ml
Storage Conditions
Storage Conditions:
10 mM Tris-HCl
1 mM EDTA
pH 8.0 @ 25°C
Storage Temperature:
-20°C
Notes
General notes:- pGPS2.1 will not replicate in ordinary lab strains of E. coli. Its origin of replication is from the transmissible plasmid R6K, and it depends on a replication initiation protein of plasmid origin (the protein product of the pir gene) not normally present in laboratory strains (4,5).
Quality Control for Current Lot

GPS Control Reaction::
A 20 µl GPS Control Reaction was performed using 0.02 µg pGPS2.1, 0.08 µg Control Target plasmid and 1 µl TnsABC* Transposase in 1X GPS Buffer supplemented with 15 mM Start Solution after 10 minutes. The reaction was incubated for 1 hour at 37°C and transformed into chemically-competent E. coli (1 x 107 per µg pBR322). Less than 1% of the resulting chloramphenicol-resistant colonies contained cointegrate molecules.
