Pro 5-alpha, JM109 and HB101 Competent Cells

Pro 5-alpha can be used for the efficient transformation of unmethylated DNA derived from PCR, cDNA and many other sources (hsdR). The elimination of nonspecific endonuclease I (endA1) enables the highest quality plasmid preparations. The strain is resistant to phage T1 (fhuA2) and suitable for blue/white screening by α-complementation of the β-galactosidase gene. Single-use Pro 5-alpha Competent Cells are available in high efficiency at greater than 109cfu/µg.

JM109 and HB101 Competent Cells are prepared according to a modified procedure of Hanahan.

JM109 is a K strain that is recA– and ...
