CGSC Strain#: 6526
Strain Designation: KLC438      Source of Strain: J.W. Chase
Sex: F- Chromosomal Markers: λ^-, thyA36, IN(rrnD-rrnE)1, rha-8, melA7, amp-50, deoC2, met-184
Strain Comments:

• thyA36-- 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.
• IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
• met-184-- leaky Met requirement
