High efficiency, chemically competent E. coli cells ideal for construction of gene banks or generation of cDNA libraries using plasmid-derived vectors
Library Efficiency DH5α Competent Cells are a versatile strain of chemically competent cells that are used in many everyday cloning applications.
Subcloning Efficiency DH5α Competent Cells are a versatile, chemically competent strain for cloning that provides a transformation efficiency of >1 x 106 cfu/μg plasmid DNA.
MAX Efficiency™ DH5α Competent Cells are a well-known, versatile strain that is used in many everyday cloning applications. Prepared by a proprietary modification of the Hanahan method, these cells are suitable for high efficiency transformations in applications where low amount of DNA is used or to construct libraries using plasmid-derived vectors.
Suitable for the expression of non-toxic heterologous genes. The strain contains the lambda DE3 prophage that carries the gene for T7 RNA polymerase under control of a lacUV5 promoter, allowing expression of the T7 RNA polymerase to be induced with IPTG.
One Shot BL21 Star (DE3) Chemically Competent E. coli are designed for applications that require high-level expression of non-toxic recombinant proteins from low copy number, T7-promoter-based expression systems such as Champion pET vectors.
One Shot Mach1 T1 Phage-Resistant Chemically Competent E. coli are the fastest growing chemically competent cells with a doubling time approximately 50 minutes.
MAX Efficiency DH10B Competent Cells are highly efficient E. coli suitable for a variety of molecular biology applications. This strain is one of the most commonly used strains for everyday applications due to key strain features such as high transformation efficiency.
One Shot TOP10 Electrocomp E. coli cells are ideal for high-efficiency cloning and plasmid propagation. Provided at a transformation efficiency of >1 x 1010 cfu/ ÎĽg supercoiled DNA, these cells allow for stable replication of high copy number plasmids.
