Na+ CP type IXα rabbit pAb

What it means: Polyclonal antibodies are produced by multiple B-cell clones, each recognizing a distinct epitope on the target protein — giving Polyclonal antibodies a broad epitope coverage.

Why it matters:

• Polyclonal antibodies typically deliver stronger signal in Western blot and IHC because multiple epitopes remain accessible even after SDS denaturation or fixation, reducing the risk of a false-negative result.
• Greater tolerance for antigen sequence variation across species makes Polyclonal reagents well-suited for studies that span human, mouse, and rat samples in the same experiment.

How to interpret here: Expect robust, high-sensitivity detection with this Polyclonal antibody. Because multiple clones contribute to the signal, titrate carefully — the optimal concentration may be lower than expected. Lot-to-lot variation is possible; validate each lot against a known-positive control.

What it means: This antibody was raised in Rabbit, producing high-affinity IgG with long CDR3 loops that confer exceptional epitope recognition. Anti-rabbit HRP, fluorochrome, and biotin secondary antibodies are universally available across all major suppliers.

Why it matters:

• The Rabbit host species determines which secondary antibody you need for indirect detection — select an anti-Rabbit IgG secondary matched to your detection label (HRP, fluorochrome, or biotin).
• Rabbit-derived antibodies pair optimally with anti-rabbit secondary antibodies. Avoid using rabbit-derived secondary antibodies in experiments involving rabbit tissue — use species-absorbed secondaries or recombinant secondaries instead.

How to interpret here: Confirm availability of an anti-Rabbit secondary antibody in your lab before ordering. For multiplex IF, pair this Rabbit-raised antibody with antibodies from a different host species to avoid secondary antibody cross-reactivity.

What it means: Validated reactivity to Human, Mouse, Rat — this antibody cross-reacts with orthologs from multiple species within a single reagent.

Why it matters:

• Cross-species reactivity (Human, Mouse, Rat) allows direct comparison of the same target across Human, Mouse and Rat experimental models without switching antibodies, eliminating an important source of inter-study variability.
• All listed reactivities are experimentally confirmed, not computationally predicted — critical for reviewers and reproducibility standards.

How to interpret here: Confirm that your specific species is among the validated list (Human, Mouse, Rat). Reactivity to unlisted species should be independently validated before use in publication-quality data.

What it means: IgG is the immunoglobulin class and subclass of this antibody, defining its constant-region structure and effector functions.

Why it matters:

• Isotype IgG determines which secondary antibody constant-region specificities are compatible — isotype-specific anti-IgG1 or anti-IgG2a secondaries enable discrimination of co-stained antibodies from the same host species in multiplex experiments.
• For functional assays, isotype identity guides selection of Fc-receptor binding controls and isotype-matched negative controls required for rigorous experimental design.

How to interpret here: Use a negative control of the same isotype (IgG) to assess non-specific binding in your assay. If performing multiplex staining with multiple antibodies from the same species, select isotype-specific secondary antibodies to resolve each IgG signal independently.

What it means: This antibody has been experimentally validated for 4 applications: Western Blot, IHC, IF/ICC, ELISA.

Why it matters:

• Western Blot
• IHC
• IF/ICC
• ELISA
• Each listed application represents an independently optimized protocol — not a theoretical prediction — giving you confidence that the antibody will perform reliably when used at the recommended conditions for that technique.

How to interpret here: Select the application that matches your assay (Western Blot, IHC, IF/ICC, ELISA) and refer to the datasheet for the validated dilution range specific to each technique. Using this antibody outside the listed validated applications requires independent optimization and performance verification.
