Direct Synthesis of ESBO Derivatives-18O Labelled with Dioxirane
This work addresses a new approach developed in our laboratory, consisting in the application of isolated dimethyldioxirane (DDO, 1a) labelled with ¹⁸O for synthesis of epoxidized glyceryl linoleate (Gly-LLL, 2). We expect that this work could contribute in improving analytical methods for the determination of epoxidized soybean oil (ESBO) in complex food matrices by adopting an ¹⁸O-labelled-ep...
متن کاملThe preparation of biotin-labelled hyaluronidase
Centre and purified using the appropriate Synsorbs (Chembiomed Ltd., Alberta, Canada). Monoclonal anti-A was isolated in the M.R.C. Human Biochemical Genetics Unit. In one experiment lactase from two individuals of different blood group (A and 0) was purified by immunoaffinity chromatography as described in Potter et al. (1985). Using the A blood-group specific antibodies and the lectin from He...
متن کاملPreparation of Biotin-labelled Toxoplasma Antigen
A method for the simple preparation ofbiotin-labelled toxoplasma antigen was used with avidin peroxidase in an IgM-capture enzyme linked immunosorbent assay (BAM-ELISA). Although the overall predictive value ofa positive result was only 38%, its low-cost and 100% sensitivity makes it a very suitable screening test. Positive results can be confirmed by an alternative assay, thus providing a more...
متن کاملA facile preparation of trisubstituted amino-furan and -thiophene derivatives.
β-Alkylation of amino-furan and -thiophene heterocycles is described through metal-, acid- and base-free carbon-carbon bond formation. The ability of both heterocycles to undergo selective β-alkylation is compared by mean of experimental and theoretical data. The presence of chiral amine substituents induced the diastereoselective generation of the newly formed additional stereocenter.
متن کاملThe preparation of 59 Fe-labelled transferrin for ferrokinetic studies.
Serum labelled with (59)Fe for ferrokinetic studies should contain only [(59)Fe] transferrin. [(59)Fe] ferric citrate was incubated at 37 degrees C for up to 24 hours with sera having an excess latent iron-binding capacity. The results showed that unbound [(59)Fe] ferric citrate may be present for several hours. An anion exchange resin (IRA 400 Cl(-)) column removed all the [(59)Fe] ferric citr...
