BL21 Chemically Competent Cells, 20x 60ul

CODE: GBBL-1

Price : $125.00

BL21 chemically competent cell, 20x60ul.>107 efficiency. BL21 competent cells are a general expression host for use with most promoter systems such as lac, trc, tac, and araD. Rec+ phenotype allows for robust growth. Lon and ompT protease mutations minimize product degradation.

BL21-DE3 Chemically Competent Cells, 20x60ul

CODE: GBBL-2

Price : $135.00

BL21-DE3 chemically competent cells, 20x60ul. >107 efficiency. BL21 (DE3) competent cells are a general purpose host for T7 vector protein expressions. They are DE3 lysogens containing the T7 RNA polymerase gene under control of the lacUV5 promoter. Induction with IPTG allows production of T7 RNA polymerase which then directs the expression of the target gene located downstream of the T7 promoter in the expression vector. The strain is deficient in lon and ompT proteases

JM109 Chemically Competent Cell, 20x100ul

CODE: GBJM-20

Price : $135.00

JM 109 Competent cells, 20 x 100ul. Efficiency - >1 x 108 transformants/?g pUC19. Cells are appropriate when routine subcloning or construction of cDNA libraries is desired. Cells allow for alpha-complementation of the beta-galactosidase gene for Blue/White color screening. May also be used for the production of single-stranded DNA from M13 or phagemid vectors. The strain carries recA1 and endA1 markers to minimize recombination and enhance quality of plasmid DNA. Includes pUC19 control plasmid for monitoring transformation efficiencies. Supplied in 20x100 ?L aliquots
