区别是基因型不一样,也可以提取质粒,参考下面:
大肠杆菌DH5α:
F-endA1 glnV44 thi-1 recA1 relA1 gyrA96 deoR nupG Φ80dlacZΔM15 Δ(lacZYA-argF)U169,hsdR17(rK- mK+), λ–
An Hoffman-Berling 1100 strain derivative (Meselson68)
Promega also lists phoA
nalidixic acid resistant

大肠杆菌S17-1 Genotype: recA pro hsdR RP4-2-Tc::Mu-Km::Tn7
Growth Conditions: Protocol: plus trimethopirm (10 mcg/ml)
Temperature: 37.0°C
Applications: transformation host
Comments: Recommended mobilization host for pARO180, pARO190, pARO181, and pARO191 (ATCC 77123-77126, respectively) because it contains chromosomally integrated tra genes. [29601]
A kanamycin-sensitive strain devoid of the E. coli K-12-specific restriction system allowing efficient uptake of foreign DNA. [41566]
The properties of streptomycin, trimethoprim, and spectinomycin resistance were verified.
RP4-Tc::Mu-Km::Tn7 is integrated into the chromosome. [29601]
