Plasmid DNA preparation

Leveraging an automated plasmid preparation platform, BiOligo provides high-quality plasmid DNA preparation services. We ensure the one-time extraction of over 10 μg of high-quality plasmid from various raw materials. The extracted plasmids are free from protein, residual genomic DNA, and RNA contamination, with transfection-grade DNA meeting low endotoxin concentration requirements.

Synthesis Requirements

  • Plasmid DNA should be ≥1 μg with sufficient purity, a clear electrophoresis profile, and relevant sequencing information.
  • The bacterial culture provided should be viable and delivered according to specifications.
  • If the plasmid carries resistance to antibiotics other than ampicillin, penicillin, kanamycin, or chloramphenicol, the antibiotic type and working concentration must be provided.

Experimental Process

Delivery Standards

  • Deliveries are prepared according to customer specifications.
  • Stab culture or glycerol stock containing the recombinant plasmid (please specify requirements when placing an order).
  • QC documents include: Certificate of Analysis (COA), sequence alignment report, sequencing chromatogram, and plasmid map.
