Somatostatin radioimmunoassay with 125I-Nalpha-tyrosyl-somatostatin.
Nalpha-Tyrosyl-somatostatin was synthesized and proved to be homogeneous. Radioiodination of this tyrosine-containing somatostatin analogue by either the lactoperoxidase method or the chloramine T method led to the formation of crude iodinated compound, which was purified by ion exchange chromatography on CM-Sephadex C-25 using a linear ammonium acetate buffer gradient. This purification proces...
متن کاملRadioimmunoassay of somatostatin in human plasma.
A radioimmunoassay procedure for determination of somatostatin immunoactivity in human plasma is described. Labelling of tyrosine-1-somatostatin is performed by chloramine T. Specific activity of the tracer is 1.34 mol iodine for 1 mol of somatostatin. The immunoreactivity is 85%. Antisera are produced in rabbits at a titre of 179 X 10(-12) mol somatostatin per ml antiserum. Human plasma is ext...
متن کاملSimple extraction method and radioimmunoassay for somatostatin in human plasma.
Interference by human plasma proteins in the radioimmunological determination of somatostatin was eliminated by subjecting plasma samples to acid--ethanol precipitation. The assay was performed on the lyophilized supernate from 300 microliters of human plasma, with reagents that are commercially available. Sensitivity was 2.6 pg, corresponding to 8.7 ng/L of plasma. The intra-assay CV was 8%; t...
متن کاملSomatostatin Decorated Quantum Dots Nanoparticles for Targeting of Somatostatin Receptors
Due to the unique optical properties like high brightness and narrow emission bands of Quantum dots, it is used as simple fluorescence materials in bio-imaging, immunoassays, microarrays, and other applications. To easy invistigate cell lines that overexpressed somtostatin receptors, somatostatin (SST) was conjugated with Quantum dots carrying PEG amine (Qdots-PEG-NH2). The conjugation of SST t...
