Quantibody Arrays (Quantitative)

Quantitative antibody arrays for absolute protein concentrations across multiplex panels

This format combines the specificity of a sandwich immunoassay with the multiplexing power of an array, so you can measure many targets at once from a single small sample. Capture antibodies are spotted in replicate on a glass slide, each detected with a matched biotinylated antibody and a streptavidin-conjugated fluorophore. A standard curve run alongside your samples converts signal to concentration. The result is absolute quantification of tens to hundreds of proteins with ELISA-like precision, calibrated within the validated dynamic range.

Pick by panel and sample.

1. Panel composition. Disease-focused or analyte-class panels of 50 to 1000 analytes.
2. Species. Human, mouse, rat coverage.
3. Sample matrix. Serum, plasma, supernatant each have specific protocols.
4. Quantification. In-slide standard curves give absolute concentrations.
5. Use. For publication-grade biomarker reporting Quantibody outperforms semi-quantitative C-Series; absolute concentration data simplifies cross-study comparison.
