  1. 16. Enzymatic conversion of β-mannans: Analysing, evaluating and modifying transglycosylation properties of glycoside hydrolases

    Författare :Mathias Wiemann; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; beta-mannanase; alpha-galactosidase; enzyme engineering; transglycosylation; MALDI-TOF MS; HPLC;

    Sammanfattning : Retaining glycoside hydrolases are enzymes that catalyse the breakdown down of glycans through hydrolysis. Due to the double-replacement mechanism of the retaining glycoside hydrolases (GHs), which form an intermediate with part of the glycan covalently attached to the enzyme, some GHs are able to catalyse synthesis reactions called transglycosylation.

    Sammanfattning : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. LÄS MER

  5. 19. Development and Validation of HPLC Methods for Analytical and Preparative Purposes

    Författare :Johan Lindholm; Torgny Fornstedt; Karin Caldwell; Karl-Gustaf Wahlund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; High performance liquid chromatography HPLC ; Analytical biotechnology; Sample preparation; Diode-array-detection DAD ; Mass spectrometry MS ; Validation; Preparative chromatography; Competitive isotherm parameters; Perturbation peak PP method; Kemi; Chemistry; Kemi;

    Sammanfattning : This thesis concerns the development and validation of high performance liquid chromatography (HPLC) methods aimed for two industrially important areas: (i) analysis of biotechnological synthesis and (ii) determination of adsorption isotherm parameters. There is today a lack of detailed recommendations for analytical procedures in the field of biotechnological production of drugs. LÄS MER

  7. 20. Multivariate spectroscopic methods for the analysis of solutions

    Författare :Kent Wiberg; Sven Jacobsson; Lars Nørgaard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; UV-Vis spectroscopy; Multivariate calibration; Lidocaine; Identity; Content; PLS; SIMCA; Non-column; Diode array UV spectroscopy; DAD; Control sample; High Capacity Analysis HCA ; Fluorescence spectroscopy; Albumin; Immunoglobulin G; HPLC-DAD; Prilocaine; Peak purity determination; PCA; PARAFAC; Partial separation; Curve resolution; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis some multivariate spectroscopic methods for the analysis of solutions are proposed. Spectroscopy and multivariate data analysis form a powerful combination for obtaining both quantitative and qualitative information and it is shown how spectroscopic techniques in combination with chemometric data evaluation can be used to obtain rapid, simple and efficient analytical methods.
