Thyroxine-binding globulin biosynthesis in isolated monkey hepatocytes. 1976

D Glinoer, and M C Gershengorn, and J Robbins

Thyroxine-binding globulin biosynthesis was demonstrated in hepatocytes isolated from normal adult Rhesus monkeys. Dispersed cells were obtained by in situ liver perfusion with collagenase, hyaluronidase and EDTA. Conditions for optimum cell survival and incorporation of radioactive leucine into newly synthesized proteins were defined. Protein synthesis, and specifically thyroxine-binding globulin synthesis, were shown to continue throughout the incubation period, while cell survival remained high (75% excluded trypan blue after 6h). Incubation medium, cytosol and a particulate fraction (extracted with digitonin) were analyzed for thyroxine-binding globulin. After extensive dialysis and purification by affinity chromatography, newly synthesized thyroxine-binding globulin was identified by specific double-antibody immunoprecipitation and by immunodiffusion and immunoelectrophoresis with autoradiography. Newly synthesized thyroxine-binding globulin was present after 4 h of incubation. After 6 h, the total synthesized had increased to 150% of the 4 h value, while the fraction present in the medium and increased to 300%, indicating probable thyroxine-binding globulin secretion

UI	MeSH Term	Description	Entries
D007122	Immunoelectrophoresis	A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D007930	Leucine	An essential branched-chain amino acid important for hemoglobin formation.	L-Leucine,Leucine, L-Isomer,L-Isomer Leucine,Leucine, L Isomer
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
