Sticky ends from different BanII sites may not be compatible.
BmgBI  (462)
1 site
C A C G T C G T G C A G

This recognition sequence is asymmetric, so ligating blunt ends
generated by BmgBI will not always regenerate a BmgBI site.
BaeGI  (419)

G K G C M C C M C G K G

Sticky ends from different BaeGI sites may not be compatible.
Bme1580I  (419)

G K G C M C C M C G K G

Sticky ends from different Bme1580I sites may not be compatible.
BsrBI  (404)
1 site
C C G C T C G G C G A G

This recognition sequence is asymmetric, so ligating blunt ends
generated by BsrBI will not always regenerate a BsrBI site.
BsrBI is typically used at 37°C, but can be used at temperatures
up to 50°C.
Bpu10I  (400)
1 site
C C T N A G C G G A N T C G

Efficient cleavage requires at least two copies of the Bpu10I
recognition sequence.
This recognition sequence is asymmetric, so ligating sticky ends
generated by Bpu10I will not always regenerate a Bpu10I site.
Sticky ends from different Bpu10I sites may not be compatible.
NaeI  (363)
1 site
G C C G G C C G G C C G

Efficient cleavage requires at least two copies of the NaeI
recognition sequence.
BsrFI  (361)
1 site
R C C G G Y Y G G C C R

Efficient cleavage requires at least two copies of the BsrFI
recognition sequence.
After cleavage, BsrFI can remain bound to DNA and alter its
electrophoretic mobility.
NgoMIV  (361)
1 site
G C C G G C C G G C C G

Efficient cleavage requires at least two copies of the NgoMIV
recognition sequence.
SfiI  (358)
1 site

Efficient cleavage requires at least two copies of the SfiI
recognition sequence.
Sticky ends from different SfiI sites may not be compatible.
SfcI  (339)
1 site
C T R Y A G G A Y R T C

Sticky ends from different SfcI sites may not be compatible.
SfcI quickly loses activity at 37°C, but can be used at 25°C for long
incubations.
BseRI  (244)
1 site
G A G G A G ( N ) 8 N N C T C C T C ( N ) 8

Sticky ends from different BseRI sites may not be compatible.
BseRI quickly loses activity at 37°C.
Prolonged incubation with BseRI may lead to degradation of the
DNA.

Sticky ends from different BtgI sites may not be compatible.
BsaHI  (125)
