, metB1Strain Comments:
- This strain was made in the Zoology Department at Columbia University, but we do not know its original designation.
- thyA2-- 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.
