Fast-T1 is currently the fastest growing competent cell. Outer membrane receptor mutation (tonA) confers resistance to lytic phage T1 and T5 in competent cells; deletion of endonuclease (endA) increases the yield and quality of plasmid DNA; recombinase deficiency (recA) reduces inserts The probability of homologous recombination ensures the stability of inserted DNA; lacZΔM15 makes Fast-T1 competent cells available for blue-white screening. The company’s Fast-T1 competent cells are prepared by a special process, and the pUC19 plasmid is used to detect the transformation efficiency ≥108 cfu/μg DNA.   Fast growth: clones can be seen after 8-9 hours of culture on ampicillin-resistant plates; single clones cultured overnight in 2 ml of LB liquid medium can be cultured for 4-5 hours to extract a small amount of plasmid DNA; Compatible resistance: T1 and T5 phage resistance; Simple operation: for ampicillin-resistant plasmids and ligation products, rapid transformation can be completed in 5 minutes   Store at -70°C (do not store in -20°C or liquid nitrogen!)

This product is prepared from chemically competent cells for cloning using a modified Inoue method, which enhances the transformation efficiency of large fragments of DNA and greatly increases the growth rate of host bacterial cells. The transformation efficiency exceeds 108 cfu/μg, which is widely used in plasmid transformation, gene cloning, blue-white spot screening and other purposes. Improved Escherichia coli enhances the transformation efficiency of large fragments of DNA and greatly increases the growth rate of host bacteria cells. Genotype Δ(mcrA)183 Δ(mcrCB-hsdSMR-mrr)173 endA1 supE44 thi-1 recA1 gyrA96 relA1 lacTetr Hte [F′ proAB lacI qZΔM15 Tn10(Tet r) Amy Camr]   XL10 strain, resistant to tetracycline (Tetr) and chloramphenicol (Camr), a new cloned strain; Suitable for efficient conversion of PCR products, cDNA and other sources of unmethylated DNA; EndA1, RecA1 mutations ensure the stability of foreign DNA in the host bacteria and facilitate the extraction of high-quality plasmid DNA; Hte genotype, enhances the transformation efficiency of large fragments of DNA, and greatly increases the growth rate of host bacterial cells; No foreign plasmid DNA residue, transformation efficiency ≥108 cfu/μg pUC19   Store at -80°C (do not store in -20°C or liquid nitrogen!)

The DH5α strain is the most commonly used competent cell in the laboratory. The deletion of endonuclease (endA) improves the yield and quality of plasmid DNA; the defective recombinase (recA) reduces the probability of recombination of inserts and ensures the stability of inserted DNA; the existence of lacZ ΔM15 makes DH5α available Screening for blue and white spots. The company's DH5α competent cells are produced through a special process, and the transformation efficiency of pUC19 plasmid detection is ≥108 cfu/μg DNA.   Suitable for efficient conversion of PCR products, cDNA and other sources of unmethylated DNA; EndA1, RecA1 mutations ensure the stability of foreign DNA in the host bacteria and facilitate the extraction of high-quality plasmid DNA; Can be used for blue and white screening of recombinant plasmids; Transformation efficiency≥108cfu/μg pUC19 DNA   Store below -70°C (do not store in -20°C or liquid nitrogen!)
