The OmniMAX™ 2 T1 Phage-Resistant (T1 R ) E. coli strain is an improved chemically competent cell line, perfect for use in all cloning applications, including the Gateway® Technology. OmniMAX™ 2 -T1 R cells offer the highest transformation efficiency of any chemically competent cells in a One Shot® format with >5 x 10 9 transformants/µg pUC19. They also provide efficient transformation of highly methylated DNA, since OmniMAX™ 2 -T1 R cells lack the E. coli K12 restriction systems (mc rA Δ (mrr hs dRMS- mc rBC)). In addition, the strain carries the to nA genotype, which confers resistance to T1...
