Product Description
Interleukin-6 (IL-6) is a pleiotropic cytokine that plays a central role in the equine inflammatory response, immune regulation, tissue injury, and exercise-induced stress. Accurate quantitation of IL-6 in horse-derived samples is essential for research in equine immunology, infectious disease, sports medicine, and veterinary science.
The Yanda-Horse-IL-6 kit is a solid-phase sandwich ELISA. A recombinant antibody specific for equine IL-6 is pre-coated onto the microplate. Standards and samples are added to the wells, followed by an HRP-conjugated detection antibody. After washing, a TMB substrate solution produces a colorimetric signal proportional to the amount of IL-6 bound. The absorbance is read at 450 nm, and sample concentrations are interpolated from the standard curve.
Validated Sample Types & Dilution Guidance
| Sample Type | Recommended Dilution | Notes |
|---|---|---|
| Equine serum | 1:2 | Directly assay at 1:2 dilution. Further dilute if readings exceed the top standard. |
| Plasma (EDTA or heparin) | To be determined by pilot experiment | Perform a preliminary dilution series to establish the optimal factor. |
| Bronchoalveolar lavage fluid | To be determined by pilot experiment | Often measurable at low or no dilution; optimization advised. |
| Cell culture supernatant | To be determined by pilot experiment | Dilute as needed based on expected secretion levels. |
| Tissue homogenate | To be determined by pilot experiment | Clarify supernatant by centrifugation; keep samples cold. |
Important: For any sample type not listed, we strongly recommend running a spike-and-recovery and linearity-of-dilution pilot study to determine the appropriate dilution factor that brings readings within the 1.0–480 pg/mL range.

Assay Procedure Summary
- Equilibrate: Bring the foil pouch to room temperature for 20 min. Remove the required strips and reseal the unused portion in the provided bag; store at 4°C.
- Add Standards & Samples:
- Standard wells: Add 50 µL of each standard.
- Sample wells: Add 10 µL of sample followed by 40 µL of Sample Diluent.
- Blank well: Leave empty.
- Add Detection Antibody: Dispense 100 µL of HRP-conjugated detection antibody into each well (except blank). Cover with a plate sealer and incubate at 37°C for 60 min.
- Wash: Aspirate the liquid, blot the plate on absorbent paper, and fill each well with 1× Wash Buffer. Let stand for 1 min, then discard. Repeat for a total of 5 washes (an automated plate washer may be used).
- Substrate Reaction: Add 50 µL of Substrate A and 50 µL of Substrate B to each well. Incubate at 37°C in the dark for 15 min.
- Stop & Read: Add 50 µL of Stop Solution to each well. Read the optical density at 450 nm within 15 min.
Total hands-on time: approximately 2 hours.
Materials required but not supplied:
- Microplate reader capable of measuring absorbance at 450 nm
- 37°C incubator or water bath
- Deionized or distilled water (for wash buffer dilution)
- Single- and multi-channel pipettes with tips
- Absorbent paper, reagent reservoirs, and general laboratory consumables
Throughput
| Format | Max. number of samples (single wells) | Includes |

Frequently Asked Questions
Q: How should tissue homogenates be prepared?
A: Homogenize tissue in ice-cold PBS (supplemented with protease inhibitors if desired). Centrifuge at 10,000 × g for 10 minutes at 4°C and collect the supernatant. Perform a pilot dilution experiment to ensure readings fall within the standard curve. Avoid repeated freeze-thaw cycles.
Q: What if my sample reads above the highest standard?
A: Dilute the sample further with the provided Sample Diluent, re-assay, and multiply the result by the dilution factor.
Q: Can this kit be used with equine cerebrospinal fluid or synovial fluid?
A: These sample types have not been internally validated. We recommend performing a spike-recovery and linearity experiment in your matrix of interest to verify compatibility.
Q: Are reagents from different kit lots interchangeable?
A: No. The components within each kit lot are calibrated as a set. Do not mix reagents from different lots or kits.
