About Cytokine & Immunoassay ELISA Kits
Cytokines sit at pg/mL, they are labile, and they behave differently in serum, plasma and supernatant — so the same sample can give two different numbers. Every human-reactivity kit here states its detection range, lower limit of detection, validated sample matrix and assay format on its product page, so you can match the kit to your sample and your expected cytokine level before you run the plate. Use the filters to narrow by target, sensitivity and sample type.
Choosing a cytokine ELISA: standard vs high-sensitivity vs antibody-pair
Most cytokine irreproducibility is a handling, matrix and sensitivity problem, not a biology problem. These three formats trade sensitivity, hands-on effort and flexibility differently. Match the format to how low your cytokine sits and to the matrix you actually collected.
| Decision dimension | Standard sandwich ELISA | High-sensitivity ELISA | Antibody-pair / DIY set |
|---|---|---|---|
| Best when the target is | Induced / stimulated cytokine at readily detectable levels | Low basal cytokine near the detection limit (e.g. resting-serum IL-6) | Any level, when you want to build and tune your own plate |
| Typical sensitivity (LLOD) | Low pg/mL (often < 1 pg/mL) | Down to ~0.04–0.11 pg/mL (kit-dependent) | Depends on the pair and coating you set up |
| Typical detection range | ~10–100 pg/mL (kit-dependent) | Sub-pg/mL to low pg/mL | User-defined by standard curve |
| Validated matrix | Serum, plasma (heparin / EDTA / citrate), cell-culture supernatant | Serum, plasma, supernatant — matrix stated per kit | Set by your own validation |
| Format & hands-on time | Pre-coated plate, sandwich, ~2–4 h | Pre-coated plate, sandwich, ~2–4 h | Coat-your-own; longer setup, most flexible |
| Best for | Routine cytokine quantitation with a known signal | Defending a small, real change in a low-abundance cytokine | Assay development, custom throughput, cost at scale |
| Watch-outs | May not reach a basal cytokine near zero | Confirm the stated LLOD covers your lowest expected value | Requires in-house optimisation and QC |
How to read this table. Pick on the stated number, not the general category. If your cytokine sits close to zero in resting samples — the classic IL-6 case — a kit that states a sub-pg/mL limit lets you call a real change a standard kit would miss. Circulating IL-6 carries a month-to-month CV of roughly 27–31% in healthy subjects, so only a change of about 60% (twice the variation) should be read as a true shift — run duplicates and keep a known control on every plate.
Browsing wider: see High-Sensitivity ELISA Kits for the lowest detection limits across all targets, Microsample ELISA when sample volume is tight, and Immunology ELISA Kits or Mouse / Murine ELISA Kits for other species and the full immunoassay catalog.
