In present study, novel magnetic molecularly imprinted polymers for hesperetin were successfully prepared by surface molecular imprinting method using functionalized Fe3O4 particles as the magnetic cores. Hesperetin as the template, N-Isopropylacrylamide as the functional monomer, ethylene glycol dimethyl acrylate as the crosslinker, 2,2-azobisisobutyonnitrile as initiator and acetonitrile-methanol...
In present study, magnetic molecularly imprinted polymers (MMIPs) were successfully prepared for specific recognition and selective enrichment of phloridzin from the leaves of Malus doumeri (Bois) A. Chev and rats' plasma. The magnetic Fe3O4 were prepared by the solvothermal reaction method and followed by the modification of TEOS and functionalization with APTES. Using functionalized Fe3O4 particles...
Immunoassay for cancer biomarkers plays an important role in cancer prevention and early diagnosis. To the development of immunoassay, the quality and stability of applied antibody is one of the key points to obtain reliability and high sensitivity for immunoassay. The main purpose of this study was to develop a novel immunoassay for ultrasensitive detection of cancer biomarker alpha-fetoprotein (AFP)...
Nanobodies that are small and thermally stable, as well as have high expression level, are leading alternative to produce anti-idiotypic antibodies. These antibodies have the advantage of replacing mycotoxins and their conjugates for immunoassays. In this work, anti-fumonisin B1 (FB1) monoclonal antibody (mAb) was used as the target for biopanning from a naïve alpaca nanobody (Nb) phage display library...
In the treatment of diabetes mellitus, glibenclamide and puerarin may be co-administered unwittingly or wittingly. An ultra performance liquid chromatography–tandem mass spectrometry method was developed to determine the concentrations of glibenclamide and puerarin in rat plasma for the study of pharmacokinetic interaction between them. Analytes were extracted using liquid–liquid extraction. The separation...
A simple competitive enzyme-linked immunosorbent assay (cELISA) was established for rapid measurement of secretory immunoglobulin A (sIgA) in saliva. The method was based on competitive reaction between the immobilized IgA and free IgA in the solution for the limited amount of horseradish peroxidase-conjugated rabbit anti-human IgA. In comparison with the conventionally used Sandwich ELISA, the cELISA...
Forward selection improved radial basis function (RBF) network was applied to bacterial classification based on the data obtained by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The classification of each bacterium cultured at different time was discussed and the effect of parameters of the RBF network was investigated. The new method involves forward...
