    At Biogem we have experience in bioanalysis; we work in compliance with regulatory guidelines and our internal procedures are designed on this basis. Nonetheless, we have the flexibility to meet customer-specific analytical requirements procedures. Where needed, our methods are validated to meet EMA and/or ICH guidelines.

    Also, following the inspection of the Italian Ministry of Health, we are GLP certified.

    As a result, we can provide complete in vitro data packages concerning the Test Items under investigation. In particular, our expertise ranges in the following areas:

    ·        Technologies

    ·        Cell Based Assays

    ·        In Vitro Enzyme assays

    Liquid chromatography coupled with different types of detector:

    ·        UV/Visible/Fluorescence;

    ·        Mass spectrometric, either single or multiple stage.

    ·        Chromatographic separations of proteins based on their hydrophobicity (reverse phase HPLC), electric charge properties (ion exchange HPLC) or size (size exclusion HPLC);

    ·        Affinity-based separation methods:

    ·        Affinity capture based on paramagnetic affinity media (e.g. Dynabeads™);

    ·        Gel-based affinity chromatography.

    ·        Protein chemistry as a sample preparation strategy for structural characterization of proteins. These strategies include:

    ·        reduction and alkylation of disulfide bonds for separation of protein chains (e.g. L and H chains of antibodies);

    ·        derivatization strategies for either protein immobilization or for sample tagging;

    ·        incorporation of stable isotopes for fine characterization of covalent structure (e.g. incorporation of stable isotopes; an example is incorporation of 18O into tryptic peptides for identification of the C-terminal peptide, elucidation of amino acid sequence, degradations/post-translational modifications).

    ·        High resolution mass spectrometry. For analysis of small molecules, the main application is metabolite profiling. On the other hand, applications to biopharmaceuticals include definition/confirmation of amino acid sequence, post-translational modifications, structural degradations, oligosaccharide structure. Normally, MS is interfaced with HPLC in order to allow hyphenated analytical schemes: like LC/MS and LC/MS/MS; alternatively, nano-LC chromatography (a miniaturized chromatography based on columns with internal diameter size of 75 m) can be used when high sensitivity or proteomics type of analysis is needed.

    ·        Statistics and data pharmacokinetic analysis (compartmental and non-compartmental).

    ·        Classes of molecules:

    ·        Small molecule drugs;

    ·        Biopharmaceuticals, including monoclonal antibodies and their derivatives.

    ·        Fields of application

    ·        Biomolecules. Application of this methodological expertise finds use in analysis of several properties of biomolecules, including the following:

    ·        Analysis of degradations and post translational modifications;

    ·        Aggregation studies;

    ·        Analysis of contaminants, product- or process-related, host cell proteins;

    ·        Analysis of covalent structure: protein sequence, glycosylation structure of glycoproteins.

    ·        In vitro ADME: species comparisons for appropriate pre-clinical animal model selection.

    ·        In vivo Pharmacokinetics: studies are done in mouse and rat animal models. Services include:

    ·        Analysis of biological matrices like plasma, urine, bile, CSF and tissues;

    ·        Drug and/or metabolite(s) profiles vs administration route.

    ·        Method transfer and optimization;

    ·        Drug formulation support.

    ·        Bioanalysis at different development stages of a biopharmaceutical. During the development of a biopharmaceutical, this set of skills is applies at different stages:

    ·        Characterization (ICH Q6B);

    ·        Comparability (ICH Q5E);

    ·        Pharmacokinetics;

    ·        Stability.
