↵1-i SDs are shown for the three time points, 24, 240, and 432 hr, which had three animals.
The concentration of [14C] derived from [14C]-radiolabeled ISIS 2922, the percent of the radiolabel coeluting with intact ISIS 2922 on HPLC, and the concentration derived by multiplying those two parameters, are shown over time after a single intravitreal injection of 66 μg of [14C]-ISIS 2922.
