2025
Multiplex fluorescence immunoassays are becoming a reference for serology testing. Their application, however, is limited by the complexity and time-consuming bead-analyte coupling processes. This report presents a semi-automated, reproducible multiplex microsphere bead coupling protocol that is comparable to the standard method while considerably reducing time to results.

Using Luminex Corporation’s xMAP microsphere technology, we have developed the Multiplexed Fluorometric ImmunoAssay (MFIA) for serosurveillance of various laboratory animal species. The MFIA is a suspension microarray where antigen, tissue control or immunoglobulins are covalently linked to color-coded polystyrene microspheres. The MFIA testing method as well as various troubleshooting topics is addressed.

Introduction to Serological Pipettes and Pipettors

2023
The serological pipette is frequently used in the laboratory for transferring milliliter volumes of liquid, from less than 1 ml to up to 50 ml. The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable. Both kinds of pipettes use a pipet-aid, for the aspiration and dispensation of liquids. Different sizes of pipettes can be used with the same pipet-aid for a variety of experimental assays. For example, serological pipettes are useful for mixing chemical solutions...

When working in a laboratory, it is imperative to minimize sources of contamination. Aseptic technique refers to procedures that permit transfer of cultures and reagents while avoiding contact with non-sterile surfaces. Serological pipettes and micropipettors are used to measure precise volumes without compromising sterility of solutions used in experiments.
FAQs
Coded beads or spatially separated array locations preserve the identity of each capture reagent while targets bind in parallel. After binding, labeled detection reagents generate signals associated with those identities, allowing the instrument to distinguish responses for individual markers. This organization enables simultaneous comparison without treating all immune reactions as one combined measurement.
Capture reagents provide target-specific binding sites, while labeled detection reagents make the captured reaction measurable. The resulting instrument signal is interpreted according to the reagent or array location linked to that target. Because each component contributes a separate identification or measurement function, assay performance depends on maintaining those distinctions across the panel.
Cross-reactivity occurs when reagents interact with unintended molecules or when signals overlap among targets. Validation therefore checks whether each measured response can be attributed to the intended antibody, antigen, or other immune marker. This is especially important for differential diagnosis or immune-pattern assessment, where inaccurate signals could distort comparisons across related markers.
Multiplexed serological testing can conserve sample volume while producing a coordinated profile of related immune markers. A single-analyte assay answers one target question at a time, whereas the multiplex format supports parallel comparison within the same specimen. That broader profile may help investigators examine patterns relevant to differential diagnosis, surveillance, vaccine responses, or autoimmune and inflammatory studies.
The workflow uses a patient sample, target-specific capture reagents, labeled detection reagents, and an instrument that reads the resulting signals. Targets are allowed to bind to their corresponding coded beads or spatial array locations, detection labels are introduced, and the instrument records reactions by target identity. The measured pattern can then be compared across markers.
Its applications include supporting differential diagnosis, monitoring infections through surveillance efforts, studying vaccine or immune responses, and evaluating autoimmune or inflammatory patterns. The value differs by question: parallel markers can reveal a broader immune profile, while interpretation still requires attention to assay validation and the meaning of each signal within the panel.
