Intact Genomics (ig) Stable 2 Electrocompetent E. coli cells offer the highest transformation efficiencies of ≥2 x 10^10 cfu/µg plasmid DNA which are ideal for applications requiring high transformation efficiencies, such as cDNA or gDNA library construction. Stable 2 cells are capable of cloning methylated genomic sequences, retroviral sequences and direct repeat sequences. Intact Genomics Stable 2 cells provide superb transformation efficiency, allowing for increased opportunity for experimental success.ig Stable 2 Electrocompetent Cells have the following features: Stable 2 allows for cloning of methylated genomic sequences Stabilizes retroviral and direct repeat sequences including HIV High transformation efficiency allows aids in cloning rare sequences May be used for plasmids > 20 kb endA1 mutation increases plasmid yield significantlyIncludes and Storage: ig Stable 2 Electrocompetent Cells: -80 ºCpUC19 control DNA: -20 ºCRecovery medium: 4 ºC
