Gyrolab CDs:
Tiny technology. Big capability.

Running immunoassays at nanoliter-scale reduces sample requirements and reagent consumption by up to a hundredfold.

The individual microstructures of Gyrolab CDs ensure precise volume definition which eliminates pipetting errors and the risk of cross-talk. Samples are processed under uniform conditions to maximize reproducibility and reliability.

Gyrolab Bioaffy CDs

Gyrolab Bioaffy CD structureUsing Gyrolab Bioaffy CDs, you can easily develop robust nanoliter-scale immunoassays exhibiting broad dynamic ranges. The CDs minimize reagent and sample consumption and deliver highly reproducible results in less than an hour. Bioaffy CDs offer full flexibility in assay design to quantify any protein, providing you have a suitable binding pair (biotinylated capture and Alexa Fluor® detection reagents).

Select the appropriate Bioaffy CD for a specific immunoassay based on the required dynamic range, the analyte concentration, the quality of reagents and the assay format. Gyrolab Bioaffy 200 CD is the starting point for the majority of applications. Assays can easily be transferred between the different CD types to accommodate wide ranges of analyte concentrations. Contact Gyros for assistance with your assay development needs.

Gyrolab Mixing CD

Mixing_CD_structureGyrolab Mixing CD integrates and automates sample pretreatment into the assay workflow made possible by Gyrolab platforms. Automating sample pretreatment and immunoassay workflow at nanoliter scale creates a number of advantages including:

  • Reduced hands-on time for complex sample pretreatments
  • Flexibility in assay design
  • Consistent and reliable sample handling
  • Reduced requirements for reagents and samples
  • 96 microstructures/Gyrolab Mixing CD

Key applications:

In Gyrolab automated method for detection of leached MabSelect SuRe™ ligands and native Protein A , samples are acidified in Gyrolab Mixing CD 96 to dissociate protein A-IgG complexes. The amount of Protein A is then determined by a sandwich immunoassay.

Another key application for Gyrolab Mixing CD 96 is ADA analysis. The mixing function can be used to incorporate the sample pretreatment, involving acid dissociation, into the automated workflow. Miniaturization makes detecting anti-drug antibodies simple, even in the presence of a high drug concentration. The individual microstructures integrate the acid dissociation process to minimize variation between samples. Dedicated Gyrolab ADA software supports assay development and validation for cut point determination, screening and confirmatory analysis.
