Pavonis Diagnostics — VICA™ platform

Compare candidate

Study biomolecular interactions under the conditions that matter to your research with VICA™, Pavonis’s label-free binding platform. Have our team run a study for you, or work with us to develop a suitable test and purchase a VICA™ reader and assay kits for use in your own lab.

How VICA™ works

See what binds,then how it behaves

VICA™ makes binding visible through colour changes on an assay slide. As molecules bind to the colour-active surface, they change how it reflects light, and the VICA™ Lightbox reads that change by eye or camera.

The assay determines what you can learn from that result. With small samples and a choice of formats, Pavonis can design studies to assess binding, specificity, binding affinity (KD) or association and dissociation rates (kon and koff).

Compare experiments on the same slide

Compare experiments on the same slide

VICA™ supports multiple experiments on one slide, with reuse for suitable assays. Running comparisons on the same surface supports consistent, direct analysis of how different molecules and conditions influence binding.

Multiple experiments · Slide reuse · One surface

Follow successive binding steps

Add proteins in sequence and observe the changing layers, so you can assess what has bound before the next addition. VICAlign™ supports oriented capture on the surface.

Test under relevant conditions

Compare behaviour in the sample media your research involves. The suitable preparation and measurements depend on the assay and matrix, which Pavonis reviews before proposing the study.

Consider research beyond the laboratory

The compact optical readout supports portable research setups, so selected assays can be taken to where the samples are collected.

 

In a completed commercial-feedlot project, veterinarian Dr. Michael Jelinski worked with Pavonis researchers to investigate a VICA™ prototype for measuring haptoglobin, a marker associated with bovine respiratory disease.

Where VICA™ fits

Compare candidates beforefurther characterization

A binding study can help narrow the candidates you take into more extensive characterization. This is one way to use VICA™ within discovery; the methods and order depend on the question your team needs to answer.

I

Design or select candidates

Identify the candidates and binding question you want to investigate.

II

Screen with VICA™

Pavonis tests physical samples using the agreed assay and conditions, providing binding evidence for comparison.

III

Shortlist candidates for further study

Use the results alongside your other evidence to decide which candidates merit more work.

IV

Characterize with established methods

Including SPR or BLI — investigate the shortlisted candidates in greater depth with methods suited to the remaining questions.

Sample conditions

Test under the conditionsyour research involves

Compare behaviour in the sample media your research involves. Whether an assay is suitable depends on the target and matrix together, so Pavonis reviews preparation, background signal and controls before proposing the measurement.

Investigating protein interactions

Researchers used VICA™ alongside other methods to examine binding between apolipoprotein A1 and matrix metalloproteinase-2. The study shows how VICA™ binding measurements contributed to a broader investigation of how these proteins interact.

The opportunity

Invest in wider accessto binding analysis

Research teams can have promising questions without the equipment, specialist operators or budget needed to investigate them. Pavonis is building its business around making binding analysis accessible to more of those teams, starting with paid pilot and service studies.

Our Edmonton-based team brings together scientific research, thin-film manufacturing and technology commercialization. Published research and customer work demonstrate how VICA™ is being used today. Assay kits and further product development are intended to support continued use as the business grows.
