Figure 4From: Fast renal trapping of porcine Luteinizing Hormone (pLH) shown by 123I-scintigraphic imaging in rats explains its short circulatory half-lifeHalf-life of 123I-pLH and 123I-eCG in rats by scintigraphy. Quantitation of emission at the level of heart was used to follow residual concentrations of radioiodinated hormones in blood. Half-life of 123I-pLH was determined by non-linear regression of relative intensities as a function of time.Back to article page
