Host should be mk+ because some packaging mixes destroy charomids by EcoK.
Useful for cloning 18-32 kb fragments.
Comments
Dimer vector can be packaged, so cosmid-type 'arm' preparation or phosphatase treatment is necessary. Host should be mk+ because some packaging mixes destroy charomids by EcoK.
IMPORTANT: To prevent amplification of a rearranged and/or deleted cosmid, we recommend streaking on LB + amp plates at 30C and picking small colonies for liquid culture.
Useful for cloning 18-32 kb fragments.
