Single-Use HB101 Competent Cells, >10(8)cfu/ug
HB101 cells are recA–, which minimizes recombination events, and contain a restriction-minus background (hsdS20) that allows better representation when cloning methylated DNA. HB101 Competent Cells are suitable for vectors that do not require ?-complementation for blue/white screening.
For researchers doing more than one transformation, competent cells are available in standard format (200µl aliquots). For added convenience, single-use competent cells (50µl aliquots) also are offered.
HB101 Competent Cells are prepared according to a modified procedure of Hanahan.
HB101 Genotype: F–, thi-1, hsdS20 (rB–, mB–), supE44, recA13, ara-14, leuB6, proA2, lacY1, galK2, rpsL20 (strr), xyl-5, mtl-1.
