Abstract

In this study, a new spectrofluorometry method was developed for the determination of human growth hormone (somatotropin) in rabbit plasma. The validation was assessed under a variety of conditions (FDA, Bioanalytical Method Validation Guidline). Calibration curves were linear between the concentration range of 0.125-8.0 μg/mL. Intra- and inter-day precision values for somatotropin in plasma were less than 13.5, and accuracy (relative error) was better than 12.0%. The recoveries for all samples were >84.0%. The limits of detection (LOD) and quantification (LOQ) of somatotropin were 0.075 and 0.10 μg/mL, respectively. The described spectrofluorometry method has adequate sensitivity and specificity to study pharmacokinetics of somatotropin in rabbits, and could be adapted also to clinical pharmacokinetic study.

Özet

Bu çalışmada, insan büyüme hormonunun (somatotropin) tavşan plazmasında tayini için yeni bir spektroflorometri yöntemi geliştirildi. Geçerlilik FDA’nın “Bioanalitik Yöntem Validasyonu” rehberinde belirtildiği koşullarda yapıldı. Kalibrasyon eğrileri 0.125-8.0 μg/mL derişim aralığında doğrusaldır. Plazmada somatotropin için gün içi ve günler arası kesinlik değerleri %13.5’den küçüktü ve doğruluk (bağıl hata) %12.0’dan daha iyiydi. Bütün örnekler için geri kazanım >%84.0 idi. Somatotropinin belirlenebilen (LOD) ve ölçülebilen (LOQ) en düşük değeri sırasıyla 0.075 and 0.10 μg/mL’dir. Tanımlanan spektroflorometri yöntemi tavşanlarda somatotropinin farmakokinetiğini incelemek için yeterli duyarlılığa ve özgüllüğe sahiptir ve klinik farmakokinetik çalışmalara da uyarlanabilir.
