EYFP-Tag Mouse 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 Mouse, producing monoclonal-format IgG produced in mouse hybridomas, offering exceptional lot-to-lot consistency. Anti-mouse secondary antibodies are the most widely catalogued in the industry.

Why it matters:

• The Mouse host species determines which secondary antibody you need for indirect detection — select an anti-Mouse IgG secondary matched to your detection label (HRP, fluorochrome, or biotin).
• In experiments with mouse-origin samples, use anti-mouse secondary antibodies that are pre-adsorbed against mouse IgG, or switch to isotype-specific secondaries to prevent background from endogenous mouse immunoglobulins.

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

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 3 applications: Western Blot, Immunoprecipitation, IF/ICC.

Why it matters:

• Western Blot
• Immunoprecipitation
• IF/ICC
• 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, Immunoprecipitation, IF/ICC) 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.
