Ensaio de potência da alfaepoetina: Comparação de camundongos Swiss Webster, NIH, C57BL6, BALB/c com o híbrido B6D2F1

Vigilância Sanitária em Debate, 2013
Neste estudo comparamos ensaios de potência da alfaepoetina realizados com camundongos de diferentes colônias e linhagens (Swiss Webster, NIH, C57BL6, BALB/c e híbrido B6D2F1). Os testes foram efetuados com fêmeas pesando 16-18 gramas, tratadas com dose única de alfaepoetina por via subcutânea (30, 90 e 270 UI/ animal).
