Strain Comments:

• 1) This strain is to be used for non-commercial research use only. It is not intended for any animal or human therapeutic or diagnostic use.
• 2) The depositors of this strain and the CGSC assume no responsibility or liability for any special, incidental, indirect or consequential loss or damage whatsoever.
• 3) No other warranty is made, whether expressed or implied, including any warranty of merchantability or fitness for a particular purpose.
• Δ(argF-lac)169-- extends from mmuP through orfs preceding argF, through lac to mhpD, literally Δ(mmuP-mhpD)169. (Peters et al. 2003 JB 185:2017)
• Δ(argF-lac)169-- from strain Hfr3000 U169 was initially called ΔlacU169 and described as a lacZY mutation until found to include argF and lacI.
• glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
• deoR481-- A selectable phenotype of deoR mutants includes the ability to grow preferentially on minimal medium with inosine as the sole carbon source.
• gyrA96(NalR)-- resistant to 200ug/ml nalidixic acid
• gyrA96(NalR)-- GAC to AAC at codon 87
• recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
• endA1-- G to A transition mutation resulting in E208K amino acid substitution.
• glnX44(AS) was formerly called su⁺_II
• glnX44(AS) was formerly called supE44
• glnX44(AS) was formerly called glnV44
• gyrA96(NalR) was formerly called
• rfbC1 was formerly called rfbD1
• thiE1 was formerly called thi-1
• = good miniprep dsDNA quality
• AS = amber(UAG) suppressor
• NalR = Nalidix.acidResist.
