Human placental calcitonin receptors.
Receptors for the hypocalcaemic hormone, calcitonin (CT), have been identified in a membrane fraction prepared from term human placentae. Binding of 125I-labelled salmon CT (125I-sCT) to the membranes was time- and temperature-dependent, saturable (Bmax. 58 +/- 11 fmol/mg of protein), of high affinity (Kd 80 +/- 21 pM) and poorly reversible. Species-specific CTs and CT analogues competed for 12...
متن کاملTHE ISOLATION OF ENZYME TRANSKETOLASE FROM HUMAN ERYTHROCYTES: THE CHARACTERIZATION OF ITS QUARTERNARY STRUCTURE
Human erythrocyte transketolase (sedoheptulose-7-phosphate: D-glyceraldehyde-3-phosphate, glycolaldehyde transferase, E.C. 2.2.1.1.) has been isolated from erythrocytes with a specific activity of 59.84 U/mg. SDS-PAGE and SE-HPLC were used both as a measure of purity and as a preparative mean to obtain a higher degree of purity. Four protein bands corresponding to molecular weights of 32,0...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Radioimmunoassay of calcitonin in human plasma.
A sensitive, specific radioimmunoassay of calcitonin is described, suitable for measuring the hormone in peripheral plasma of normal man. With this assay we have demonstrated that calcitonin is detectable under basal Conditions and the concentrations respond to induced, and spontaneous hypercalcemia and induced hypocalcemia. The mean value for basal calcitonin of normal men was 182 pg/mI (range...
متن کاملTissue Specific Expression of Human Calcitonin Gene in Potato Tubers by an Organ Specific Promoter
To increase the production level of heterologous proteins in plants, strategies such as choice of strongerpromoters, optimization of codon usage and specific localization of foreign proteins are of major concern.Calcitonin (CT), a 32 amino acid polypeptide is a powerful and specific inhibitor of bone resorption and isused to treat several human diseases. Calcitonin activity is...
