Backbone

  • Vector backbone
    pAC-EHER
  • Backbone manufacturer
    Francis X. Cunningham, Jr.
  • Backbone size w/o insert (bp) 13581
  • Total vector size (bp) 9476
  • Modifications to backbone
    Constructed from pAC-EHER by deletion of adjacent 0.8 and 1.1 kB BamHI-BamHI frag- ments, as well as and adjacent 1.6 and 0.6 kB AvaI-AvaI fragments. This served to remove most or all of the coding regions of the idi (ORF6), crtX, crtY, and crtZ genes.
  • Vector type
    low copy number bacterial cloning vector

Growth in Bacteria

  • Bacterial Resistance(s)
    Chloramphenicol, 25 μg/mL
  • Growth Temperature
    30°C
  • Growth Strain(s)
    Top10
  • Growth instructions
    Grow liquid cultures on a platform shaker at 28 degrees Celsius for 2-3 days in darkness for best lycopene production, or grow on agar plates at room temperature for 3-7 days. Use to confirm the function of the products of prospective DXS or IPI or LytB-encoding genes or cDNAs. Active enzymes will yield E. coli colonies much darker in color [see Cunningham FX Jr, Lafond TP, Gantt E (2000) Evidence of a role for LytB in the nonmevalonate pathway of isoprenoid biosynthesis. J Bacteriol. 182, 5841-5848.]. Use pAtipiTrc or pdxs/ipiTrc as a positive control.
  • Copy number

Depositor Comments

For better yield of low copy number pAC-based plasmids, grow liquid cultures on a platform shaker at ca. 30 degrees Celsius. When cultures reach early stationary phase, dilute 2-fold with growth medium, add spectinomycin (150 mg/liter), and "amplify" for several hours before harvest. For plasmid selection and maintenance in E. coli, use chloramphenicol at 30 mg/liter.

Purpose

Ready-to-use, high-purity DNA prep. DNA aliquots are suitable for use in mammalian cell transfections and other molecular biology applications.

Delivery

  • Amount 50 μg
  • Concentration 1 μg/μL
  • Pricing $495 USD
  • Storage 4 ℃ (short-term) or -20 ℃ (long-term)

Terms and Licenses

  • Academic/Nonprofit Terms
  • Industry Terms
    • Not Available to Industry

Quality Control

Every DNA prep is verified by next-generation sequencing, confirming plasmid identity, sequence integrity, and absence of DNA contaminants. Concentration is confirmed to be within ±2.5% of the stated concentration.

Our production process has been validated to consistently yield endotoxin levels below 1.0 EU/μg. Individual lots are not tested for endotoxin.
