Human IgG ELISA kit

What it means: Assay format describes how the ELISA is designed. This kit uses a Sandwich ELISA, in which the analyte is captured between two antibodies recognising different epitopes.

Why it matters:

• A Sandwich ELISA delivers high specificity because two independent antibodies must bind the same target molecule.
• It produces a quantitative result read against a standard curve, suitable for measuring defined antigens in research samples.
• The format gives a wide working range and good reproducibility when standards and samples are run consistently.

How to interpret here: This kit is a Sandwich ELISA, so expect a specific, quantitative readout derived from a standard curve run on the same plate.

Tip: Run standards and samples in duplicate on every plate for reliable quantitation.

What it means: The target analyte is the specific molecule this kit is built to measure — Human IgG.

Why it matters:

• The kit is optimised specifically for Human IgG and is not intended to detect unrelated molecules.
• Analyte identity defines which sample types and research questions the kit is appropriate for.
• Knowing the exact analyte lets you confirm the assay matches your experimental endpoint.

How to interpret here: This kit quantifies Human IgG; confirm that this is the analyte and matrix relevant to your study.

Tip: Verify your sample type is compatible with the kit before running a full plate.

What it means: Detection describes how assay signal is generated and read. This kit uses colorimetric detection with TMB (3,3′,5,5′-tetramethylbenzidine) substrate.

Why it matters:

• Colorimetric TMB detection is read on a standard absorbance plate reader at 450 nm, with no specialised equipment needed.
• It produces a stable, quantitative endpoint signal proportional to the amount of captured analyte.
• The widely used TMB chemistry makes the assay easy to adopt and compare across laboratories.

How to interpret here: Results are read colorimetrically with TMB substrate; a standard absorbance plate reader is sufficient to obtain quantitative data.

Tip: Add stop solution and read the plate promptly for the most reproducible absorbance values.

What it means: Quantification describes how sample values are derived. This kit is quantitative: sample signal is interpolated from a standard curve of known analyte concentrations.

Why it matters:

• A standard-curve approach converts raw absorbance into actual concentration values rather than relative signal.
• Including the standard series on each plate corrects for plate-to-plate and day-to-day variation.
• Quantitative output supports rigorous comparison between samples, treatments and experiments.

How to interpret here: This kit gives standard-curve-based quantification, so prepare and run the supplied standards on every plate.

Tip: Fit the standard curve with an appropriate model (often 4-parameter logistic) for accurate interpolation.
