Nuclear T3 binding sites were detected in the whole brain and lung of chick embryos. Gel chromatography on Sephadex G-100 of the solubilized receptors showed an identical elution profile (peak 1: T3 nonspecifically bound; peak 2: T3 bound to the receptor; peak 3: free T3). The sedimentation coefficient on glycerol density gradient was 4.0S for both receptors, and the estimated mol wt is 60,000. Scatchard analysis performed with purified nuclei and the solubilized receptors revealed a single class of binding sites. The values of the association constants (Ka) and the maximal binding capacities (MBC) at 17 days of embryogenesis were as follows (mean ± SD): brain: purified nuclei, Ka = 0.64 ± 0.1 × 109 M-1, MBC ± 1.44 fmol/μg DNA; solubilized receptor, Ka = 1.16 ±0.1 × 109 M-1, MBC = 1.95 ± 0.08 fmol/μg DNA; lung: purified nuclei, Ka = 0.77 ± 0.1 ± 109 M-1 MBC = 2.72 fmol/μg DNA; solubilized receptor, Ka = 2.02 × 109 M-1, MBC = 1.86 ± 0.1 fmol/μg DNA. Serial studies performed at different days of embryogenes...
