TfR1/CD71 (5C9) monoclonal antibody

What it means: Clonality describes how an antibody is produced and how many distinct epitopes it recognizes on the target antigen. A Monoclonal antibody is generated from a single B-cell clone, so it binds one precisely defined epitope on the antigen.

Why it matters:

• Monoclonal antibodies deliver excellent lot-to-lot consistency and a defined, reproducible epitope specificity.
• Single-epitope binding gives low background and suits quantitative and multiplexed assays.
• Clonality directly influences assay selection, expected background, reproducibility, and how cross-reactivity should be interpreted in your experiment.

How to interpret here: Because this product is supplied as a Monoclonal antibody, expect precise, epitope-specific detection that is ideal for comparative, quantitative, and reproducibility-critical experiments.

Tip: Confirm the validated applications and recommended dilutions, and titrate the antibody in your own system for the best signal-to-noise ratio.

What it means: Host species is the animal in which the antibody was raised. The immune system of the host generates the antibody against the target antigen. This antibody was produced in Mouse.

Why it matters:

• The Mouse host determines which secondary antibody is required for detection — the secondary reagent must be an anti-Mouse conjugate.
• In multiplex or co-staining experiments, the Mouse host must differ from the host of every other primary antibody to prevent secondary cross-reactivity.
• The host species also influences potential background when staining tissue or cells of the same species, which may require additional blocking.

How to interpret here: Because the host is Mouse, pair this antibody with an anti-Mouse secondary conjugate matched to your detection method, and plan panel design so no two primaries share the Mouse host.

Tip: Keep a record of the host species when designing multi-colour panels to avoid avoidable cross-reactivity artefacts.

What it means: Reactivity lists the species (or antigens) whose target this antibody is documented to detect, based on the supplier's validation data. Documented reactivity here is Human, Mouse, Rat.

Why it matters:

• Reactivity confirms whether this antibody is suitable for your experimental model (Human, Mouse, Rat).
• Species or antigens not listed have not been validated by the supplier and should not be assumed to react without independent confirmation.
• Reactivity often tracks with the sequence conservation of the immunogen region across species.

How to interpret here: You can use this antibody with confidence for the listed reactivity (Human, Mouse, Rat); for any species or antigen that is not listed, run an appropriate positive control to verify epitope conservation before relying on the result.

Tip: Compare the immunogen sequence with your species of interest when planning work outside the documented reactivity.

What it means: The conjugate is any detectable label, enzyme, or tag chemically attached to the antibody so that bound antibody can be visualized or quantified. This antibody is supplied Unconjugated.

Why it matters:

• An unconjugated antibody carries no label, so detection requires a separate labelled secondary antibody or an enzymatic detection system.
• The unconjugated format is the most flexible option — the same primary antibody can be reused across chromogenic, fluorescent, and chemiluminescent workflows.
• Signal amplification through a secondary reagent can substantially improve sensitivity for low-abundance targets.

How to interpret here: Because this antibody is supplied Unconjugated, plan your detection chain around a compatible labelled secondary antibody that matches your intended readout, and verify the secondary is raised against the correct host species.

Tip: Match the label or detection chemistry of this Unconjugated antibody to your imaging or assay platform before starting, and protect fluorescent conjugates from light.

What it means: This field lists the laboratory techniques for which the antibody has documented, supplier-validated use. The validated applications here are Western Blot.

Why it matters:

• Each validated application (Western Blot) has its own optimal antibody dilution, sample preparation, and control requirements.
• Validation in a given application means the supplier has confirmed specific detection under those experimental conditions.
• Using the antibody outside the validated applications (Western Blot) requires independent optimization and additional controls.

How to interpret here: Select this antibody when your workflow uses one of the listed applications, and follow the recommended dilution provided for each technique.

Tip: Always titrate the antibody in your own samples — optimal dilution can vary with tissue, fixation, and detection system.

What it means: Purity indicates the proportion of the preparation that is the intended antibody, typically assessed by SDS-PAGE or chromatography. This product is specified as > 95% (by SDS-PAGE).

Why it matters:

• A higher purity specification (> 95% (by SDS-PAGE)) means fewer contaminating proteins, which reduces non-specific background and improves signal clarity.
• Consistent purity supports reproducibility across lots and is important for sensitive quantitative assays.
• Well-purified antibody preparations behave more predictably when optimizing dilutions.

How to interpret here: A purity of > 95% (by SDS-PAGE) indicates a well-defined preparation suitable for the validated applications listed for this product.

Tip: Store the antibody exactly as directed to preserve both purity and binding activity over its shelf life.
