MxB 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, Rat, Mouse — this antibody cross-reacts with orthologs from multiple species within a single reagent.

Why it matters:

• Cross-species reactivity (Human, Rat, Mouse) allows direct comparison of the same target across Human, Rat and Mouse 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, Rat, Mouse). 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 2 applications: Western Blot, IHC.

Why it matters:

• Western Blot
• IHC
• 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) 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.
