The MULTI‑SPOT format supports up to 10‑plex cytokine profiling per well, delivering exceptionally clean signals even in challenging matrices like serum, cerebrospinal fluid, and tissue lysates. With no‑wash, rapid workflows and user‑friendly software, MSD® streamlines high‑precision assays for pharmaceutical development, translational studies, and low‑volume or low‑abundance biomarker research.

Key Advantages:

• Femtogram sensitivity (≤ 0.05 pg/mL)
  
• 10‑plex multiplexing per well
  
• Excellent matrix tolerance (CSF, lysates, serum)
  
• No‑wash, fast workflows
  
• High signal‑to‑noise for reliable quantification

ELISA: Single-Analyte Assay

The enzyme‑linked immunosorbent assay (ELISA) is the classic method for cytokine detection, using a capture antibody, target analyte, and enzyme‑linked detection antibody to generate a colorimetric or chemiluminescent readout. While limited to one analyte per well, its simplicity, reproducibility, and compatibility with standard microplate readers make ELISAs a good first step. Then follow with multiplex (Luminex) assays to analyze multiple biomarkers simultaneously to gain a broader view of the immune environment. Typical sample volumes range from 50–100 µL per well, but ELISA’s low kit cost and widespread availability ensure cost‑effective results.

Key Advantages:

• Universally available kits and reagents
• Easy implementation and low complexity in any lab with a plate reader
• Cost‑effective for small to medium sample sets
• High reproducibility for single‑analyte verification
• Flexible detection modes (colorimetric or chemiluminescent)

Performance Comparison: Luminex® vs MSD® vs ELISA

Choosing the right multiplex cytokine assay requires balancing sensitivity, dynamic range, sample volume, throughput, cost, and matrix tolerance. Here’s a streamlined comparison to help you decide between Luminex®, MSD®, and traditional ELISA.

1. Sensitivity & Dynamic Range

One of the most critical aspects of cytokine profiling is the ability to detect low-abundance analyte – especially in inflammatory diseases or immunotherapy research.

• MSD® leads in sensitivity, detecting analytes in the femtogram per milliliter (fg/mL) range. This ultra-sensitivity is ideal for femtogram level expectations or picogram level expectations with limiting samples volume.
  
• Luminex® offers picogram-level sensitivity, striking a balance between performance and multiplexing. It covers a wide dynamic range (~3–4 logs), sufficient for most exploratory studies.
  
• ELISA typically provides accuracy within a narrower dynamic range (2–3 logs), and sensitivity can vary based on kit quality, often within the low picogram range.

2. Sample Volume

In studies where available samples are limited – such as pediatric cohorts, animal models, or rare biological fluids – sample volume becomes a deciding factor.

• Luminex®: 25 µL per well profiles up to 96 cytokines.
• MSD®: 25–50 µL per well for up to 10 analytes; no‑wash options conserve even more.
• ELISA: 50–100 µL per well per analyte. Less efficient when screening multiple targets.

3. Throughput & Cost

In high-throughput environments or exploratory profiling phases, the number of analytes detected per well can influence overall workflow efficiency.

• Luminex®: Highest throughput (100‑plex), moderate cost per well, 4–6 hr assay time.
• MSD®: Mid‑throughput (10‑plex), higher per‑sample cost, 2–4 hr no‑wash workflows.
• ELISA: Single‑plex only, low kit cost but linear cost scaling and 3–5 hr hands‑on time.

4. Workflow & Scalability

Cost matters – especially when processing hundreds of samples or optimizing conditions in pilot studies.

• Luminex® and MSD®: Outsourced services eliminate capital investment; scalable to hundreds of samples. Requires dedicated instrument/training but offers rapid, user‑friendly software.
• ELISA: Universal protocols fit any standard lab; scaling means more plates and manual steps.

Practical Considerations in Choosing a Cytokine Assay

Beyond sensitivity and throughput, the practical side of assay selection can often determine success in immunology and biomarker discovery projects. Researchers must consider how well a platform handles complex samples, how it fits into their lab workflow and available labware, and whether it allows for flexibility in assay design. Below, we explore matrix interference, workflow integration, and customizability factors.

1. Matrix Interference: Performance in Real-World Sample Types

In cytokine profiling, biological samples such as serum, plasma, and tissue lysates often contain interfering substances that can affect analyte detection. A platform’s ability to minimize matrix effects is crucial for obtaining accurate and reproducible results.

• Luminex®: Offers reliable performance across common matrices like serum and plasma. However, matrix interference may arise with certain low-abundance cytokines, especially in more complex fluids. Careful panel design and validated protocols help improve consistency. Pre-analytical pre-treatment of some sample types may be required.
  
• MSD®: Known for its strong performance in challenging matrices due to its electrochemiluminescence detection system, which tolerates the sample matrix better than other platforms. Ideal for studies requiring ultra-sensitive detection in complex biological fluids.
  
• ELISA: Typically robust in simple matrices but may require additional sample preparation for tissue lysates or high-protein content samples. Since it’s usually a single-analyte assay, optimizing each ELISA for the sample type is essential.

2. Technical Support & Workflow Integration

How well an assay platform integrates into your lab’s workflow depends on available resources, required expertise, and the desired turnaround time. Choosing a platform with accessible technical support and flexible workflow options can significantly streamline your study.

• Luminex®: Highly scalable and compatible with both in-house and outsourced workflows. At Eve Technologies, we offer Luminex-based multiplex cytokine assays as a service—no instrumentation needed on your end.
  
• MSD®: Offers strong manufacturer support and user-friendly software. While installation and initial training are more involved, the platform is accessible for most molecular biology labs with standard equipment and personnel.
  
• ELISA: Minimal setup required, with reagents and kits widely available. Best suited for labs with basic equipment or researchers validating a small number of targets.

3. Customizability: Off-the-Shelf Kits vs Tailored Cytokine Panels

The ability to build a custom cytokine panel is critical for targeted discovery and cost-efficiency, especially when you’re focused on specific biomarkers or pathways.

• Luminex®: One of the most customizable multiplex platforms available. Researchers can select individual analytes to create a fully personalized panel, reducing costs and conserving sample volume.
  
• MSD®: Supports custom panel development, but flexibility may be limited based on available antibody pairs and detection formats. More suitable for semi-custom panels built from pre-qualified analytes.
  
• ELISA: Offers the least flexibility for multiplexing, as each cytokine requires its own assay. While individual ELISA kits can be mixed and matched, multiplexing is not feasible without additional optimization.

Luminex®: Best for Medium- to High-Plex Cytokine Panels

Luminex® is ideal when you need to measure 15–96 cytokines at once, making it a top choice for autoimmune studies, vaccine development, and immuno-oncology. Its bead-based multiplexing conserves sample while delivering robust data across large panels.

MSD®: Best for High-Sensitivity Cytokine and Biomarker Detection

MSD® is a go-to platform when you need ultrasensitive detection. It’s especially powerful for studies where biomarkers are present in low concentrations – such as early disease detection, treatment monitoring, or clinical research where precision is everything.

At Eve Technologies, we’ve seen firsthand that some analytes consistently perform better on MSD® than on other platforms. RANKL is a perfect example.

RANKL plays a critical role in bone remodeling and immune regulation. Abnormal expression is linked to conditions like osteoporosis, rheumatoid arthritis, bone metastases, and certain cancers. When clients needed better RANKL data, MSD® outperformed every time – so much so that we launched Human MSD® Discovery Assay® RANKL (MSDHRANKL).

ELISA: An Option for Analytes Outside Luminex® and MSD® Panels

There are some important analytes that simply aren’t available on Luminex® or MSD® platforms. In these cases, we can run ELISA-based assessments for you.

ELISA is not our preferred platform, but we understand it’s sometimes necessary. We purchase commercially available kits and perform the assay in-house. Since ELISA kit quality can vary between manufacturers, and different manufacturers may use different antibody pairs, results may differ depending on the specific kit used. That’s why we go through every detail with you ahead of time—so you know exactly what to expect.

If you’re targeting a unique analyte not covered in our multiplex panels, we’ll help you determine if ELISA is the best option for your project.
