Human IL17 (Interleukin 17) CLIA Kit for Quantitative Detection

What it means: CLIA (Chemiluminescent Immunoassay) is an antibody-based quantitative detection format using a chemiluminescent substrate to generate a measurable light signal proportional to analyte concentration.

Why it matters:

• CLIA typically provides higher sensitivity than conventional colorimetric ELISA, enabling detection of low-abundance analytes in complex matrices.
• Luminescent signal detection offers broader dynamic range and reduced interference from colored or turbid samples compared to absorbance-based methods.

How to interpret here: This kit uses CLIA format and requires a luminometer or compatible multimode reader for signal detection. Analyte concentration is interpolated from a standard curve supplied with the kit.

What it means: Chemiluminescence is the signal readout method used in this CLIA kit. An HRP-conjugated detection antibody reacts with the substrate to emit photons quantified by luminometer.

Why it matters:

• Chemiluminescent detection provides lower detection limits than colorimetric absorbance methods, enabling quantification at picogram-per-milliliter concentrations.
• The signal is not susceptible to colored matrix interference that can compromise OD-based assays.

How to interpret here: Detection requires a luminometer capable of reading relative light units (RLU) from 96-well microplates. Results are derived from RLU measurements interpolated against a standard curve using the provided standards.

What it means: This CLIA kit has been analytically validated for use with Serum.

Why it matters:

• Using validated sample matrices ensures reliable quantification within the stated dynamic range. Unvalidated matrices may cause non-specific interference or inaccurate results.
• Sample handling (collection tube, anticoagulant, freeze-thaw history) can significantly affect assay performance. Follow the protocol recommendations closely.

How to interpret here: Your samples should match the validated type (Serum). Samples from non-validated matrices should be tested with spike-recovery experiments before reporting quantitative results.

What it means: The sensitivity of this kit is 7.5pg/mL, representing the lowest analyte concentration that can be reliably distinguished from zero.

Why it matters:

• Samples expected to contain concentrations below this threshold cannot be accurately quantified and should be reported as below the limit of detection (BLD).
• High assay sensitivity is critical when studying analytes present at very low concentrations in biological fluids, such as early-disease biomarkers or tissue-derived mediators.

How to interpret here: A sensitivity of 7.5pg/mL means samples below this concentration fall outside the quantitative range. For samples near the LLOQ, replicate measurements are recommended to confirm results.

What it means: The quantitative detection range of this kit is 12.5~800pg/mL, defining the concentration window within which accurate results can be obtained from the standard curve.

Why it matters:

• Samples must fall within this range for reliable quantification. Samples above the upper limit must be diluted before re-testing; samples below the lower limit should be reported as BLD.
• The calibration range should bracket the expected concentrations in your sample type and disease condition to avoid extrapolation errors.

How to interpret here: Ensure your undiluted (or pre-diluted) sample concentrations fall within 12.5~800pg/mL. Samples above the upper limit require serial dilution; results should be multiplied by the dilution factor.

What it means: The total assay duration for this CLIA kit is approximately 3.5 hours, encompassing all incubation, wash, and detection steps.

Why it matters:

• Accurate timing is critical for CLIA performance. Deviation from specified incubation times can shift the standard curve and affect sample results.
• Plan your experiment to ensure luminometer availability and that all reagents are equilibrated to the recommended assay temperature before initiating the protocol.

How to interpret here: Allocate approximately 3.5 hours of uninterrupted bench time per assay run. Automation of wash steps can improve throughput in high-volume settings.

What it means: This CLIA kit is validated for Human samples and detects the Human form of the target analyte.

Why it matters:

• Antibody reagents in species-specific immunoassays are raised against the target species' antigen. Cross-reactivity with orthologous proteins from other species cannot be assumed.
• Using a human-specific kit to measure mouse or rat samples (or vice versa) will likely yield inaccurate or undetectable results unless cross-reactivity has been experimentally confirmed.

How to interpret here: This kit is appropriate for Human research samples only. For non-human primate, rodent, or other species, confirm cross-reactivity data or use a species-matched kit.
