Description

IG® Ultra-High Efficiency Electrocompetent E. coli Cells

Intact Genomics (IG®, ig®) offers the largest collections of high-quality competent cells on the market.

Originally founded 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 and reliable performance.

Combining our scientists’ expertise and craftsmanship with state-of-the-art equipment, advanced protocols, and rigorous quality control standards, our competent cells provide the following advantages:

Exceptional Transformation Efficiency – Up to 10–100× higher than other leading brands.
Consistent Quality – Manufactured under an ISO 13485:2016-certified quality management system to ensure reliable lot-to-lot performance.
Competitive Pricing– High-performance products at affordable prices to help maximize your research budget.
Flexible Formats and Custom Services – 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.
