Anti-GFP Tag Rabbit Polyclonal Antibody

Polyclonal antibodies are a mixture of antibodies that recognize multiple epitopes on the same target. They are often chosen for strong signal and robust detection across different sample conditions.

Why buyers choose polyclonal antibodies

• Higher sensitivity: Multiple epitope binding can produce stronger overall signal.
• Epitope coverage: More tolerant to minor changes in target structure or fixation effects.
• Detection robustness: Can perform well across a wider range of sample types.

When to consider another option

• if you need maximum lot-to-lot consistency or long-term standardization
• if background is a concern in complex samples

For higher standardization and reproducibility, a monoclonal antibody (with a defined clone number) is often preferred.

Reactivity describes which species the antibody is expected to recognize based on validation and/or target sequence conservation. Reported reactivity for this product includes: Mammals, Bacteria.

Why buyers should check reactivity

• Species compatibility: Make sure your sample species is included in the reported reactivity list before ordering.
• Sequence conservation: Even when species are closely related, small sequence differences can affect binding (especially for monoclonals).
• Sample context: Tissue type, expression level, and sample prep can influence whether reactivity translates into a clean signal.

Buyer guidance

• If your species is not listed, consider requesting additional validation or testing a small pilot first.
• Use a positive control sample from a listed species whenever possible to confirm performance.
• For tag antibodies (e.g., GFP/HA/FLAG), reactivity often reflects where the tag is used rather than a native species protein—fusion design and expression level still matter.
