Chemically modified bacterial cells capable of uptaking DNA from the environment via transformation. Competent cultures of E. coli are used in the lab for various procedures including cloning, protein expression, and genetic library creation.
These Intact Genomics chemically competent DL39(DE3) E. coli cells are engineered for efficient transformation and protein expression. They support uniform and specific amino acid labeling, and reduce NMR cross-labeling via transaminase activity.

GoldBio s GV3101 Agrobacterium chemically competent cells allow you to obtain high transformation efficiency in applications such as gDNA or cDNA library construction Our GV3101 strain harbors the C58 chromosomal backbone containing rifampicin resistance and the Ti plasmid pMP90 (pTiC58DT-DNA) harboring the gentamicin resistance A functional T-DNA binary system can be built using our GV3101 strains as the T-DNA region has been deleted in the Ti plasmid and instead has a binary vector containing the missing T-region The binary system makes possible to transfer genetic material into a host plant s genome Our system is often used for Agrobacterium -mediated transformation in mono and dicotyledonous species such as Arabidopsis thaliana tobacco potato soybeans and corn
