Contraception, 42(2), 215-223 (1990-08-01)
The male mediated teratogenic potential of a new antifertility compound, styrene maleic anhydride (SMA), was evaluated in rabbits. No teratogenic potential was observed at the doses of 1.25 mg, 2.5 mg and 5.0 mg used in our experiment.

Contraception, 59(2), 137-144 (1999-06-11)
Ultrastructural changes in the vas deferens of langur monkeys after 150 days of vas occlusion with styrene maleic anhydride (SMA) and after 150 days of noninvasive reversal are reported. The vas deferens of the sham-operated control animals revealed active secretory

We present a solid-phase immobilization method for radioligand assays, using an immunoadsorption coating procedure of anti-triiodothyronine rabbit IgG (anti-T3 IgG) onto second antibody (sheep anti-rabbit IgG) covalently bound to Amino-Dylark beads. The second antibody was in excess, compared with the
