Invitrogen ProQuantum immunoassays are designed for easy-to-run, high-performance, target-specific protein detection, with no proprietary instrument to purchase. Utilizing proximity-based amplification technology, ProQuantum assays offer the analyte specificity of antibody-antigen binding with the signal detection and amplification capabilities of qPCR to achieve a highly sensitive assay. ProQuantum assays can also typically detect lower levels of protein with lower sample consumption than traditional methods.
Explore our immunoassays for different research areas, including immune-oncology, neurobiology, isotyping and immunoglobulin characterization, hallmarks of cancer, car t cells, and more.

ProQuantum immunoassays utilize a matched pair of target-specific antibodies each conjugated to a DNA oligonucleotide. This platform leverages the sensitivity and large dynamic range of Applied Biosystems TaqMan real-time PCR technology. During antibody–analyte binding, the two DNA oligos are brought into close proximity, which then allows for ligation of the two strands and subsequent creation of template strand for amplification (Figure 2).

Watch the “How to run a ProQuantum assay” instructional video for simple steps to run the assay at your lab bench.
ProQuantum Software analyzes target-specific protein quantitation results for all ProQuantum high-sensitivity immunoassay kits. The software provides end-to-end support starting with step-by-step guidance to prepare an assay run including setting up the standard curve and plate layout for 96- or 384-well plates. The analysis features include standard curve qualification, with built-in outlier detection, interpolation of unknown samples for quantitation, and group-wise statistical analysis.
