Biologics by LC-MS – Ithaca, NY

Formed in 2008, the LC-MS biologics team at Q2 Solutions is one of the few bioanalytical laboratories successfully employing both triple quadrupole and high-resolution mass spectrometry (HRMS) for biological analyte LC-MS quantitation. We lead the regulated bioanalysis CRO industry in HRMS capacity with 10 validated Quadrupole- Exactive (QE) orbitrap instruments. Extensive nano-LC capabilities together with a highly automated bead-based immunoprecipitation extraction process delivers unparalleled sensitivity and proven reproducibility. These advanced technologies and our depth of experience combine with a collaborative approach to solve your large molecule bioanalytical challenge.

Large molecule immunoassay services – Marrietta, GA and Beijing, China

Q2 Solutions offers a full range of services for the development or technical transfer and validation of custom- designed assays and application to study sample testing for PK concentration, immunogenicity and biomarker testing. Ligand binding assays (LBA), typically in the format of immunoassays, are the standard for bioanalytical testing of large molecule drugs. Formats can include use of target, anti-idiotypic antibodies, anti-conjugate, enrichment approaches, and competitive assays depending on drug design and characteristics of the drug and reagents. Platforms including chromogenic ELISA, chemiluminescence, fluorescence and electrochemiluminescence that provide the standard basis for macromolecule drug testing.

Quantitative concentration assays

  • PK concentration (Free, Total, Complex)
  • Biomarker for analytes that will be used to make regulatory decisions and for label instructions
  • Immunogenicity   (Anti-Drug Antibody)
    • Screen/Confirm/End Point Titer
    • Domain Specificity/Isotyping
    • Neutralizing (Competitive LBA and Cell-based).

Additional services include critical reagent conjugation and characterization, immunogenicity cut point statistical reports.

ADME Services – Indianapolis, IN

Q2 Solutions helps customers evaluate in vitro properties and in vivo plasma/tissue exposures to optimize ADME properties for potential drug candidates and assess risk associated with metabolism and drug-drug interactions (DDI).
