My CHO-K1 cells were completely killed by 200 U/mL of Calbiochem hygromycin
B after a 72 hour exposure.  However, I have some mutatn strains derived
from CHO-K1 that were slightly more sensitive to hygromycin B.  In
both cells strains, I was able to use 200 Units per milliliter to select
transfected cells.  I use the pCEP4 vector carrying hygromycin resistance.
