General Cloning & Library Construction

E. cloni® 10G and 10GF' Chemically Competent Cells » Clone, subclone, propagate plasmids. Transform using heat shock.

E. cloni® 10G and 10GF' Electrocompetent Cells » Construct libraries, perform general cloning, product ssDNA.

E. cloni® 5-alpha Chemically Competent Cells » Clone, subclone. Transform using heat shock.

Low Endotoxin Cells

CleanColi™ BL21(DE3) Electrocompetent Cells »

Eliminate endotoxin at the source. These genetically modified E. coli competent cells lack the key signal for triggering pro-inflammatory cytokines and immune system activation. Significantly decreases the time, cost and effort related to endotoxin removal while increasing the reliability of experimental results.

Custom Competent Cells
