CGSC Strain#: 2527
Strain Designation: AB2527      Source of Strain: G. Eggertsson
Sex: F- Chromosomal Markers: lacY1, tsx-59, glnV44(AS), gal-6, λ^-, hisG1(Fs), thyA3, argG6, xyl-7, ilvD132
Strain Comments:

• thyA3-- Strains with this marker must have their medium supplemented with thymine (25ug/ml). This is true even for rich medium such as LB. Otherwise thymine starvation can lead to thymineless death.
• glnV44(AS) was formerly called supE44
• glnV44(AS) was formerly called su⁺_II
• xyl-7 was formerly called xylA7
• AS = amber(UAG) suppressor
• Fs = Frameshift mutation
