Invitrogen™ TOP10 Electrocomp™ Kit
Description
TOP10 Electrocomp E. coli cells are provided at a transformation efficiency of 1 x 1010 cfu/μg supercoiled DNA and are ideal for high-efficiency cloning and plasmid propagation. This strain is used in wide range of applications and allows stable replication of high-copy number plasmids and maintenance of large plasmids.
The TOP10 genotype is similar to the DH10B strain and features:
• hsdR for efficient transformation of unmethylated DNA from PCR amplifications
• mcrA for efficient transformation of methylated DNA from genomic preparations
• lacZΔM15 for blue/white color screening of recombinant clones
• endA1 for cleaner preparations of DNA and better results in downstream applications due to the elimination of non-specific digestion by Endonuclease I
• recA1 for reduced occurrence of non-specific recombination in cloned DNA
Notes
Please see the product manual for reaction scale recommendations. A high-voltage electroporation apparatus is required.
