Description

GoldBio’s GV3101 Agrobacterium Electrocompetent Cells are optimized for the highest transformation efficiencies which is ideal for applications requiring high transformation efficiencies, such as cDNA or gDNA library construction. The GV3101 strain has a C58 chromosomal background with rifampicin resistance and the Ti plasmid pmp90 (pTiC58DT-DNA) with gentamicin resistance. The GV3101 Ti plasmid has the T-DNA region sequences deleted and transformation with a binary vector containing the missing T-region results in a functional T-DNA binary system that allows for transfer of genetic material into a host plant S genome. Therefore, this system is often used for Agrobacterium-mediated transformation of several dicots such as Arabidopsis thaliana, tobacco, potato and soybeans as well as monocots like corn.

GoldBio’s AGL-1 Agrobacterium Electrocompetent Cells are optimized to produce the highest transformation efficiency, and are ideal for applications requiring high transformation efficiencies such as cDNA or gDNA library construction. The AGL-1 strain has a C58 chromosomal background that carries an insertion mutation in its recA recombination gene which stabilizes recombinant plasmids. It also carries rifampicin and carbenicillin resistance in its genome for selection. AGL-1 contains the Ti plasmid pTiBo542 from which the T-DNA region sequences have been deleted. Transformation with a binary vector containing the missing T-region results in a functional T-DNA binary system that allows for transfer of genetic material into a host plant’s genome. Therefore, this system is often used for Agrobacterium-mediated transformation of Arabidopsis thaliana as well as maize and other monocots.
