(11-245) Mix & Go! XJa (DE3) Autolysis Competent Cells 1 ml 500x L-Arabinose 10 x 100 ul/Unit

Description

• This strain is EndA- and yields high quality DNA preparations.
• The RecA- mutation in XJa stabilizes repetitive DNA sequences.
• Suitable for general screening, but proteases may degrade small or otherwise unstable recombinant proteins.
• Fast: 80 – 90% of E.coli are lysed in only 10 minutes after harvesting.
• Simple 20 Second Transformation: No heat shock! Just add DNA and spread.
• DE3 Lysogen: Encodes the T7 polymerase for expressing recombinant proteins under the control of the T7 promoter.
• 10^8 – 10^9 transformants per µg of plasmid DNA.
