Fabrication and Optimization of a PAGATA Gel Dosimeter: Increasing the Melting Point of the PAGAT Gel Dosimeter with Agarose Additive
Introduction: The PAGAT polymer gel dosimeter melts at 30 ˚C and even at room temperature during the summer, so it needs to be kept in a cool place such as a refrigerator. To increase the stability of the PAGAT gel, different amounts of agarose were added to the PAGAT gel composition and the PAGATA gel was manufactured. Material and Methods: The PAGATA gel vials were irradiated using a Co-60 ma...
متن کاملSeparation and size determination of human serum lipoproteins by agarose gel filtration.
A method is described for the separation of the three major classes of human serum lipoproteins by gel filtration on columns of 4 and 6% agarose gel. After calibration of the columns, the elution volumes of the lipoproteins were used to calculate the molecular sizes and molecular weights of these macromolecules. The technique was employed to demonstrate aggregation of low density lipoprotein fo...
متن کاملAgarose coated spherical micro resonator for humidity measurements.
A new type of fiber optic relative humidity (RH) sensor based on an agarose coated silica microsphere resonator is proposed and experimentally demonstrated. Whispering gallery modes (WGMs) in the micro resonator are excited by evanescent coupling using a tapered fiber with ~3.3 µm waist diameter. A change in the relative humidity of the surrounding the resonator air induces changes in the refra...
متن کاملFurther characterization of galactosylhydroxylysyl glucosyltransferase from chick embryos. Amino acid composition and acceptor specificity.
A modified purification procedure, consisting of affinity chromatographies on concanavalin A-agarose, collagen-agarose and UDP-glucose-derivative-agarose and one gel filtration, is reported for galactosylhydroxylysyl glucosyltransferase. The enzyme obtained is entirely pure when studied by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. The enzyme protein was rich in glutamic acid +...
متن کاملElectrophoretic variants of alanine aminopeptidase, alkaline phosphatase, and gamma-glutamyltransferase in urine.
The three brush-border enzymes--alanine aminopeptidase (EC 3.4.11.2), alkaline phosphatase (EC 3.1.3.1), and gamma-glutamyltransferase (EC 2.3.2.2)--are present in the urine of healthy persons in two variants, a particulate form and a soluble one. They can be separated by electrophoresis in agarose gel and by ultracentrifugation. The particulate forms exhibit similar electrophoretic mobility, b...
