Keywords:Wildlife animals, Radioimmunoassay, Progesterone, Estradiol
AbstractDPC commercial kit (Coat-A-Count - Diagnostic Products Corporation/USA) and DSL commercial kit (Diagnostic System Laboratories INC/USA) were used for progesterone and estradiol radioimmunoassay validation in serum of two endangered Brazilian felids: Leopardus pardalis (n=5) and Leopardus tigrinus (n=4) before (15-30 days) and after (24-28 hours) exogenous gonadotrophins treatment (hCG/ Novormon® and eCG/ Vetecor®; pFSH/Folltropin-V® and pLH/Lutropin-V®). Variation of estradiol concentration was 0.005 0.151 ng/ml and progesterone concentration was 0.15 - 37.22 ng/ml for Leopardus pardalis. Variation of estradiol concentration was 0.012-0.147 ng/ml and progesterone concentration was 0.15 - 37.22 ng/ml for Leopardus tigrinus. Minimum sensibility detected for progesterone was 0.004 ng/ml and for estradiol was 0.00014 ng/ml. Progesterone intra-assay coefficient was 2.58% and 6.36% and inter-assay was 0.67% and 5.55%. Estradiol intra-assay coefficient was 0.69% and 4.15%, and inter-assay was 1.40% and 3.00%. Parallelism was used for kits validation. Progesterone and DPC commercial kit Parallelism was r = 0.96 for Leopardus pardalis and r = 0.99 for Leopardus tigrinus. Estradiol and DSL commercial kit Parallelism was r = 0.98 for Leopardus pardalis and r = 0.99 for Leopardus tigrinus. In conclusion, these results showed that DPC commercial kit for serum progesterone dosages and DSL commercial kit for serum estradiol dosages can be used for Leopardus pardalis e Leopardus tigrinus. These findings are potentially valuable for the reproductive management and conservation of endangered felid populations.
