Plasmid Preparation

Sample Submission Guidelines

Sample Type Sample Guideline
Clonal Plasmid DNA 5 µl at 200 ng/µl (minimum 100 ng)
Colonies on agar <3 days old; single and well isolated
Clonal Agar stab samples agar stabs
Clonal Glycerol stocks 200 µl of frozen stock
Frozen bacterial cell pellets varies by scale

Viral Plasmid Containing Inverted Terminal Repeat (ITR)

Be aware that sequencing ITR is challenging, so we request concentrated stocks of DNA.

  • Optimal sequencing concentration for Viral Plasmid is 300 ng/µl (minimum 200 ng/µl). Please submit as much template as you are able, up to 10 µl but no less than 5 µl.
  • Please include exact concentration in Notes field for each template.
  • Ensure 260/230 ration of 1.8-2.2, as this protocol is particularly sensitive to organic contamination.
  • Primer – Please provide 30 µl per reaction at 5 pmol/µl (5 µM) in a labeled 1.5 or 0.5 ml tube.
  • Generate primers that bind between 150 bps and 350 bp from the ITR.
