Gyrolab™ Generic PK Kit

Gyrolab GPK Kit-web

The development of recombinant therapeutic IgG is often challenging, including multiple candidates per program, reagent selection and limited sample volume. Added to that, the efficacy and safety parameters of lead candidates must be evaluated in two pre-clinical species, such as mouse, rat and cynomolgus monkey. Sample volumes may be limited and analyte levels may vary greatly.

To meet these needs, Gyros has developed a pharmacokinetics kit to accurately and robustly quantify human IgG1, IgG2, or IgG4 titer over a broad range in a number of matrices and with the convenience that a ready-to-use kit brings. An additional benefit of Gyrolab technology is that an assay only consumes nanoliter volumes, which provides major benefits in preclinical work by enabling serial sampling of fewer mice to generate better data for more analyses and using less material.

Key benefits of Gyrolab Generic PK Kit

  • No need for assay development

Broad dynamic range and small sample consumption

  • Measurement range over 4 logs
  • Minimizes dilutions and repeats
  • Enables serial analysis of small animals

Meets a broad range of needs

  • Different matrices: mouse, rat, cynomolgus monkey, rabbit, and dog
  • Range of IgG classes: IgG1, IgG2, and IgG4

Assay principle

The sandwich assay is based on biotinylated anti-human IgG-Fc as capturing molecule and fluorescently labeled monkey adsorbed anti-human IgG as detection antibody. The biotinylated reagent is captured in a streptavidin column in a microstructure in the CD. Diluted sera containing intact human IgG are volume-defined and introduced into the microstructures where intact IgG is captured on the capture column and the detection reagent is added.
