Human FceRII(Receptor II For The Fc Region Of Immunoglobulin E) Microsample ELISA Kit

What it means: Target is the analyte this ELISA is designed to measure. The target on this page is FceRII (Receptor II For The Fc Region Of Immunoglobulin E).

In ELISA workflows, immunoglobulin targets are commonly used for immune status, exposure, or assay control readouts.

Why it matters:

• Correct match: Use the target name/synonym (Receptor II For The Fc Region Of Immunoglobulin E) to confirm you’re measuring the right biomarker (isoforms and closely related family members can differ).
• Species fit: This kit is listed as Human reactivity—choose a kit matched to your organism to avoid reduced binding and inaccurate quantification.
• Interpretation: Baseline abundance varies widely by tissue, treatment, and disease state—plan controls and a dilution series to keep readings within the standard curve.

How to interpret here: The chip value shows the target as FceRII (Receptor II For The Fc Region Of Immunoglobulin E). Use it to align your study design (samples, expected range, and controls) and follow the recommended standard curve and dilution guidance.

What it means: Reactivity indicates the species the antibodies/standards in the kit are validated to detect. This kit is listed as Human.

Why it matters:

• Accuracy: Species-matched reagents improve binding and reduce under-recovery caused by sequence differences.
• Sample choice: Use matrices typical for that species (e.g., serum/plasma, tissue lysate) and validate dilution to minimize matrix interference.
• Comparability: Don’t compare absolute concentrations across species unless you’ve validated equivalence with appropriate standards and controls.

How to interpret here: Choose Human when your samples come from that organism. For cross-species studies, validate each species separately to ensure comparable recovery.

What it means: A Sandwich ELISA captures the target with one antibody and detects it with a second antibody, improving specificity and sensitivity for many protein targets.

Why it matters:

• Higher specificity: Dual-antibody recognition helps reduce background from related proteins in complex samples.
• Best for proteins: Commonly used for cytokines, receptors, enzymes, and other larger analytes with multiple epitopes.
• Workflow impact: Signal typically increases with analyte concentration; follow incubation and wash steps closely to maintain signal-to-noise.

How to interpret here: The chip value Sandwich indicates a dual-antibody format—use appropriate sample dilution and thorough washing for reliable quantification.

What it means: Sensitivity is the lowest concentration the assay can reliably distinguish from background under the recommended conditions. The listed sensitivity is 0.119 ng/mL.

Why it matters:

• Low-abundance targets: Higher sensitivity (a lower number) helps when expected levels are near the detection limit.
• Plan dilutions: If samples are concentrated, dilute into the assay range; if levels are very low, optimize sample prep to improve recovery.
• Matrix matters: Real samples can reduce effective sensitivity—use matrix-matched standards or include spiking/recovery checks when possible.

How to interpret here: Use 0.119 ng/mL to judge whether the kit can detect your expected baseline levels. If you expect concentrations close to this value, run a pilot with a dilution series to confirm reliable quantification.
