Description
GeniePlex MagPro Human Neuroinflammation Comprehensive 13-Plex is a magnetic bead-based multiplex immunoassay kit for the simultaneous quantitative detection of 13 analytes from a single sample using flow cytometry. Antibody-conjugated beads with distinct fluorescence intensities capture target antigens, which are then detected via biotinylated antibodies and streptavidin-PE to produce a fluorescent signal proportional to each analyte concentration.

*Note: The below is a summary protocol. Protocols may vary by lot. Always follow the instructions included with your kit.
Standard Preparation
- Label eight 0.6 mL microcentrifuge tubes 0–7. Add 150 µL Assay Buffer to tubes 0–6. Leave tube 7 empty.
- Reconstitute the lyophilized standard: centrifuge briefly (500 × g, 10 s), add 500 µL Assay Buffer, stand 5 min, mix gently until dissolved. Transfer to tube 7 (highest standard).
- Serial dilution: transfer 50 µL from tube 7 → tube 6 (1:3.2), then 100 µL from tube 6 → 5 → 4 → 3 → 2 → 1, mixing at each step. Tube 0 = zero standard (buffer only).
Assay Procedure
| Step | Protocol |
| 1. Bead & Sample Incubation | Add 50 µL Premixed Antibody-Conjugated Beads (vortex ≥ 15 s) and 50 µL sample or standard to each well. Seal plate. Incubate on shaker at RT, 600 rpm, protected from light, 1 hour. |
| 2. Detection Antibody | Place plate on magnetic separator for 1 min, remove supernatant. Add 100 µL Biotinylated Detection Antibodies. Seal and incubate at RT, 600 rpm, protected from light, 1 hour. |
| 3. SA-PE & Wash | Magnetic separate 1 min, remove supernatant. Wash once with 200 µL Wash Buffer. Add 100 µL SA-PE. Seal and incubate at RT, 600 rpm, protected from light, 30 min. Wash twice with 200 µL Wash Buffer. |
| 4. Acquisition | Resuspend beads in 200 µL Wash Buffer. Acquire on flow cytometer using PE, APC, and APC/Cy7 channels. |
Data Analysis
- Collect at least 200 beads per analyte gate (minimum 2,600 total beads for this 13-plex panel).
- Calculate median fluorescence intensity (MFI) for standards and samples. Subtract blank MFI.
- Plot standard curve (concentration vs. MFI, log-log) and fit with a 4-parameter logistic (4-PL) model.
- Determine sample concentrations from the standard curve. If MFI exceeds the upper limit, dilute and re-measure.
