Intact Genomics GV3101 Agrobacterium Chemically Competent Cells are optimized for the highest transformation efficiencies which is ideal for applications requiring high transformation efficiencies, such as with cDNA or gDNA library construction. The GV3101 strain has a C58 chromosomal background with rifampicin resistance and the Ti plasmid pMP90 (pTiC58DT-DNA) with gentamicin resistance. The GV3101 Ti plasmid has the T-DNA region sequences deleted and transformation with a binary vector containing the missing T-region results in a functional T-DNA binary system that allows for transfer of genetic material into a host plant’s genome. Therefore, this system is often used for Agrobacterium-mediated transformation of several dicots such as Arabidopsis thaliana, tobacco, potatoes, and monocots like corn.Product Includes and Storage:GV3101 Agrobacterium Chemically Competent Cells: -80 ºCpCAMBIA1391z control DNA: -20 ºCAgro Recovery medium: 4 ºC

Intact Genomics (ig) HB101 chemically competent E. coli cells are suitable for high-efficiency transformation in a wide variety of applications such as cloning and sub-cloning. E. coli HB101 is a K12 x B hybrid strain, containing the recA13 mutation that minimizes recombination and helps insert stability. In addition, it carries the hsdS20(rB-mB-) restriction minus genotype which prevents cleavage of cloned DNA by endogenous restriction enzymes. HB101 strain does not support Alpha-complementation for blue/white screening.Reagents Needed for One Reaction:ig HB101 chemically competent cells: 50 µlDNA (or pUC19 Control, 10 pg/µl): 1 µlRecovery medium: 1 ml

Lucigens Endura Competent Cells are a commonly used strain for cloning sequences that suffer unwanted recombination events in other strains. Clones with inverted repeats or other sequences prone to recombination are commonly found in retroviral genes, and require cells such as Endura to be propagated stably.

Mix & Go E. coli cells are made chemically competent by a unique method that completely eliminates the need for heat shock and related procedures. For transformation, DNA can be added directly to Mix & Go cells and the mixture spread directly to a culture plate. Transformation efficiencies typically range from 108-109 transformants/g of pUC19 DNA, which make the cells optimal for cloning, sub-cloning, library construction, etc. Premade Mix & Go cells are supplied as a pack of 10 convenient 100 l/tube aliquots or in a 96-well format (12 x 8 - tube strips) of 50 l/tube.
