Obtaining the right clone shouldn’t be the most time-intensive step in your research. That’s why each E. coli strain from Invitrogen is specially engineered to keep you moving ahead. High transformation cloning efficiencies—ranging from >1 × 106 to >3 × 1010—ensure that you produce representative cDNA and genomic libraries every time. While other competent cells claim resistance to T1 and T5 phages, Invitrogen strains have the tonA genotype, providing the best insurance against contamination. To make sure that each lot of cells consistently gives you the highest level of performance, stringent quality control standards must be met. If your research requires competent cells, you’ll find what you need to succeed here.
