GoldBio’s AGL-1 (pSoup) chemically competent Agrobacterium cells are optimized for high transformation efficiencies, making them ideal for applications such as cDNA or gDNA library construction. These cells are resistant to rifampicin, carbenicillin, and streptomycin, providing versatility in selection and antibiotic resistance. The Ti plasmid pTiBo542DT-DNA has been engineered to have the T-DNA region deleted, which can be complemented with a binary vector containing the missing T-region to restore the T-DNA binary system function. This feature enables efficient and precise transformation of plant genomes.

AGL-1 (pSoup) chemically competent cells are free of animal-derived products and grown with animal-free media.

The pSoup plasmid present in these cells is required for the replication of pGreen, 62SK, and pGs2 series plasmids, increasing the range of applications for the AGL-1 (pSoup) system. These competent cells are suitable for Agrobacterium-mediated transformation of dicots such as Arabidopsis thaliana, tobacco, potato, as well as monocots like corn, making them an ideal choice for plant molecular biology research.

GoldBio’s AGL-1 Agrobacterium chemically competent cells allow you to obtain high transformation efficiency in applications such as gDNA or cDNA library construction. Our AGL-1 strain harbors the C58 chromosomal backbone with an insertion mutation in its recA recombination gene. This mutation stabilizes recombinant plasmids. AGL-1 also has rifampicin and carbenicillin resistance genes in the genome useful for selection. A functional T-DNA binary system can be built using our AGL-1 strains as the T-DNA region has been deleted from the Ti plasmid pTiBO542 and instead it has a binary vector containing the missing T-region. The binary system makes possible to transfer genetic material into a host plant S genome. Therefore, our system is often used for Agrobacterium-mediated transformation in mono and dicotyledonous species such as Arabidopsis thaliana, maize, and other plants.

GoldBio CJ236 chemically competent E. coli cells are ideally suited for use in the Kunkel method of mutagenesis. CJ236 cells have part of their Thymine replaced with deoxyuracil in the DNA due to dut- and ung- mutations which prevent the cells from removing uracil from DNA caused by misincorporation or dCTP deamination. CJ236 contains the F’ gene which confers Chloramphenicol resistance.

CJ236 chemically competent E. coli cells are free of animal-derived products and grown with animal-free media.
