Restriction digests of the clone give the following sizes (kb): BamHI--25.0, 13.0, 9.8; EcoRI--24.0 (doublet); SalI--22.0, 9.0, 8.4, 4.4, 4.2. Vector permitting positive selection (Spi) of recombinants. Useful for generating jumping and linking libraries and conversion to phagemid (without selection). Permits construction using partial filling-in. The restriction sites to be used for conversion to phagemid are: BspMII SalI ClaI. The sizes of the major components are (kb): arms--20.3, 9.2; stuffer fragment--13.7; phagemid segments--3.9 (longer arm), 0.7. The order of the major features in this plasmid is: arm - ClaI BspMII SalI - pMB1 ori - ampR - M13 ori - SacI/MCS/SalI - stuffer - SalI/MCS/NotI - ClaI SalI BspMII - arm. |
