 E. coli & Other Chemically Competent Cells

 

Intact Genomics offers a broad selection of high-efficiency chemically competent cells for routine and specialized cloning, protein expression, phage display, recombineering, and library construction. Select strains deliver transformation efficiencies of ≥1 × 10¹° cfu/µg DNA. Manufactured under an ISO 13485:2016-certified quality system, our competent cells provide reliable, consistent performance across multiple formats, including tubes, strip tubes, and 96- and 384-well plates. Custom strains, packaging formats, bulk quantities, and OEM solutions are also available.
