Protocol

Biopharma Insights The linear covalently closed (LCC) DNA minivector (DNA ministring) is a non-viral gene delivery vector offering high transfection efficiency and is relevant to any DNA delivery application. The production system is simple, rapid, and scalable in vivo. The following protocol provides visual step-by-step instructions for the production of DNA ministrings.

Difficulty
intermediate
Total time
~24–48 hours (culture growth + induction + harvest)
Biosafety
BSL-1

Steps

1
Prepare media and bacterial cultures

Set up growth media and inoculate bacterial cultures according to protocol specifications. Ensure sterile technique and appropriate culture conditions for ministring-producing strain.

2
Execute bacterial growth phase

Grow bacterial cultures to target optical density and monitor cell density. Prepare cultures for induction of ministring production machinery.

▶ 01:58
3
Induce and harvest ministring production

Induce ministring synthesis via chemical or environmental trigger, allow production phase, then harvest cells and extract DNA ministrings using cell lysis and purification methods.

4
Verify ministring production and characterization

Analyze harvested samples to confirm successful double-stranded DNA ministring production, assess yield, and document results for non-viral gene delivery applications.
