Intact Genomics (IG®, ig®) offers the largest collections of high-quality competent cells on the market.
Founded originally as a BAC cloning company, Intact Genomics developed deep expertise in producing ultra-high-efficiency competent cells to enable transformation of very large plasmids (~300 kb) into E. coli. Over the years, this expertise—combined with continuous process optimization—has allowed us to consistently deliver exceptionally high transformation efficiencies.
Leveraging our scientists’ expertise and craftsmanship, state-of-the-art equipment, advanced protocols, and rigorous quality control standards, our competent cells provide the following advantages:
- Highest Transformation Efficiency – Up to 10–100× higher than other leading brands.
-
Quality Control – We maintain rigorous quality control measures in accordance with ISO 13485:2016 to ensure consistent reliability from batch to batch.
- Affordable– Competitive pricing to maximize your research budget.
- Format Flexibility & Custom Services Available – We offer a broader range of formats than competitors, including tubes (multiple aliquot sizes), 96- and 384-well plates, and strip tubes. We also provide custom competent cell services tailored to your specific needs.
Custom formats, custom package sizes and bulk pricing are available upon request.
