Renin release in the isolated perfused rat kidney model is curvilinear and requires 45 minutes to stabilize, indicating that sampling must be restricted to the stable phase to avoid experimental errors.
No takes yet. Share an insight, caveat, or question.
Sampling before 45 min risks error in rat kidney renin assays; leaves open standardization across perfusion models.
Epstein et al. (1979) studied this question.
