CC-110 spr-u-1-6-2 mt+
$30.00
Boynton-Gillham laboratory, Duke University
Phenotype: antibiotic resistant (spectinomycin)
This strain was derived at Duke from a cross between CC-147 nr1-8 spr-u-1-62 and CC-198 er-u-37 sr-u-2-60; it does not carry nr1-8 or the markers from CC-198.
This is a good chloroplast resistance marker, easy to score on 100 microgram/ml spectinomycin. spr-u-1-6-2 is an A to G mutation at position 1123 in the chloroplast 16S rRNA and confers high level spectinomycin resistance under all growth conditions.
