Daclizumab ELISA Kit

What it means: Assay Type describes the readout format and quantification logic of the immunoassay. For this kit the value is Quantitative Colorimetric ELISA, meaning the plate is read colorimetrically on a standard absorbance microplate reader and every sample is quantified against a calibration curve prepared from the supplied standard.

Why it matters:

• Determines how the optical signal relates to analyte concentration and how raw OD values are converted into concentrations through the standard curve.
• A quantitative format supports comparisons across treatments, time points, dose groups, and independent studies, rather than a simple positive/negative call.
• Colorimetric detection requires no special filters or luminescence module — any reader capable of 450 nm-type absorbance measurements is sufficient.

How to interpret here: Quantitative Colorimetric ELISA means concentrations are interpolated from a standard curve run on the same plate, so include the full standard series in every run.

Tip: Run standards and samples in duplicate on the same plate; comparing raw OD values between plates without a per-plate curve is a common source of error.

What it means: Sample Type describes the sample matrices in which the assay has been validated by the manufacturer. For this kit the value is Plasma, Serum, and staying inside these validated matrices is the simplest way to keep results interpretable.

Why it matters:

• Matrix composition — total protein content, lipemia, hemolysis, anticoagulant choice — can raise background or suppress signal and shift apparent concentrations.
• Using a validated matrix avoids re-validation work; results from unlisted matrices cannot be assumed comparable without checks.
• Consistent collection, processing, and storage of samples matters as much as the matrix itself for run-to-run reproducibility.

How to interpret here: Samples of type Plasma, Serum can be run following the datasheet dilution guidance directly; any other matrix should first pass dilution-linearity and spike-recovery checks.

Tip: When comparing groups, keep the matrix identical across all samples — do not mix serum and plasma results within one analysis.

What it means: Sensitivity describes the lowest analyte concentration the assay can reliably distinguish from background (the analytical detection limit). For this kit the value is 0.156 μg/mL, which sets the floor for what the kit can measure without sample concentration steps.

Why it matters:

• Determines whether low-abundance samples are measurable at all, or whether they will read as indistinguishable from the blank.
• Readings near the detection limit carry the highest variance, so study designs expecting low concentrations need more replicates.
• Comparing kits by sensitivity only makes sense together with the working range — a lower limit is not useful if your samples sit mid-range.

How to interpret here: With a sensitivity of 0.156 μg/mL, any sample expected below this level cannot be reliably quantified and should be concentrated or run with an alternative method.

Tip: Treat values between the blank and {v} as qualitative at best; report them as below the limit of detection rather than as exact numbers.

What it means: Detection Range describes the standard-curve interval over which quantification is accurate and reliable. For this kit the value is 0.31-5 μg/mL, defining where on the curve a sample must fall for its interpolated concentration to be trusted.

Why it matters:

• Samples above the range must be diluted and re-run; samples below it need concentration or a more sensitive assay.
• Precision is best in the middle of the curve — the flattening ends of the range carry noticeably more error.
• Knowing the expected physiological or experimental concentration ahead of time lets you pick a single dilution that lands mid-curve.

How to interpret here: Dilute samples so expected concentrations fall inside 0.31-5 μg/mL, ideally within the central portion of that interval.

Tip: If a sample reads above the top of {v}, do not extrapolate — repeat at a higher dilution and multiply back by the dilution factor.

What it means: Plate Format describes the physical format of the assay plate supplied with the kit. For this kit the value is 96-well (96T), the standard footprint for microplate ELISA workflows in research laboratories.

Why it matters:

• The 96-well format is compatible with standard microplate readers, washers, and multichannel pipettes without any adapters.
• It sets the well budget per run: standards, blanks, controls, and samples (ideally in duplicate) all share the same plate.
• Planning the plate layout in advance — edge effects, replicate placement, sample randomization — improves consistency between runs.

How to interpret here: 96-well (96T) provides enough wells for a full standard curve plus roughly forty samples in duplicate in a single run.

Tip: Avoid leaving partially used strips exposed; reseal unused wells with the plate cover and follow the storage guidance to preserve coating activity.
