| Shipping Information： | Shipped: xa0Freeze dried E. coli containing the plasmids |
| Comments： | There are 2 plasmids in this E. coli, pSU77 and pMT100. The pMT100 phagemid contains the modification methylase SssI from Spiroplasma sp. The pSU77 construct is necessary to suppress UGA codons at positions 229, 349, 595 and 709 that function to terminate translation in E. coli. The insert of plasmid pMT100 contains the following restriction sites (approximate kb from the 5 end): EcoRI--1.10, 1.40; EcoRV--0.81; HindIII--0.15, 0.97; SacI--0.67; XbaI--0.30. Expression of the suppressor tRNA is regulated by a lacUV5 promoter and a rrnC terminator. Restriction digests of pSU77 give the following sizes (kb): KpnI/NotI--4.6; PstI/XbaI--4.6; PstI--4.6; HindIII--4.6; EcoRI--4.2, 0.3. Restriction digests pMT100 give the following sizes (kb): KpnI/NotI--3.0, 1.5; PstI/XbaI--3.0, 1.2, 0.4; PstI--4.6; HindIII--3.0, 0.9, 0.7; EcoRI--2.3, 2.0, 0.17. |
