Agarose Conjugated Anti-V5 Tag Mouse Monoclonal Antibody (11D5)

V5 tag is a short epitope tag commonly included in expression vectors for detection of recombinant proteins. It’s often chosen as an alternative to HA/Myc/FLAG depending on vector design and compatibility.

Why buyers use anti-V5

• WB confirmation: Detects V5-tagged proteins and verifies expected size.
• IF localization: Useful for staining tagged proteins in fixed cells or tissues.
• IP enrichment: Bead-conjugated formats support IP/Co-IP workflows.

When to consider another approach

• Tag accessibility: placement and protein folding can reduce binding.
• Capture strength: if IP yield is low, FLAG/3×FLAG can be a stronger alternative in some systems.

Clone 11D5 is the unique monoclonal antibody clone designation for this product. If you previously used a V5 Tag antibody labeled “11D5,” this clone number is the key identifier that helps you select the same antibody lineage for better experiment-to-experiment consistency.

What “Clone 11D5” tells you (and what it doesn’t)

• It tells you: this antibody comes from a single monoclonal clone (11D5), meaning the antibody population is uniform and targets one dominant epitope/epitope region.
• It does not guarantee: identical performance across all suppliers, because formulation, purification, conjugation, and validation standards can differ even when the clone number matches.

When choosing Clone 11D5 is especially helpful

• Replacing an antibody: If your previous antibody was “V5 Tag (Clone 11D5),” matching the clone is the best first step to keep band patterns and background similar.
• Protocol/paper matching: Many published protocols specify the clone. Using the same clone reduces variability when reproducing literature results.
• Standardization across projects: Clone-based standardization is useful when multiple people or sites run the same workflows.

Buyer checks before committing

• Application validation: Confirm Clone 11D5 is validated for your intended assay(s) listed on the product page (e.g., WB vs IF/IHC vs IP).
• Specificity expectations: Review validation images (if available) and confirm the expected signal pattern for your sample type.
• Plan controls: If you are switching from a different clone, run side-by-side comparisons and include positive/negative controls to confirm specificity and background.

For WB, the apparent band size depends on your fusion protein (tag + protein of interest) and sample conditions.

Tip: This agarose-conjugated format is designed for IP/Co-IP workflows and can reduce background compared with using an unconjugated antibody plus secondary reagents.

Monoclonal antibodies are produced from a single B-cell clone and recognize one dominant epitope/epitope region on the target. They are often chosen for their consistent performance and lot-to-lot reproducibility.

Why buyers choose monoclonal antibodies

• Reproducibility: More consistent results across experiments and over time.
• Specificity: Typically cleaner signals when the epitope is well exposed.
• Standardization: Easier to match literature protocols when a clone is specified.

When to consider another option

• if the target epitope is masked by fixation, folding, or complex formation
• if you need broader recognition across isoforms or modified forms of the protein

In these cases, a polyclonal antibody can sometimes provide stronger overall signal because it recognizes multiple epitopes.

Application(s) indicate which experimental methods this antibody has been tested/validated for. Choosing an antibody validated for your specific method is one of the best ways to reduce troubleshooting.

What the listed application(s) mean

• Immunoprecipitation (IP): Enriches target proteins (and sometimes complexes) from lysates; antibody format and bead chemistry affect yield and background.

Buyer guidance

• Match your workflow: If your main use is WB, IF, IHC-P, or IP, prioritize antibodies validated for that exact application.
• Sample prep matters: Fixation, permeabilization, antigen retrieval, and lysis buffer can change epitope accessibility and background.
• Use controls: Include positive/negative controls and, when possible, compare with a known antibody or sample.

Host refers to the species in which the primary antibody was raised (here: Mouse). Host selection mainly affects which secondary antibody you should use and can influence background in certain sample types.

Why buyers care about the host

• Secondary antibody matching: Choose an anti-mouse secondary (e.g., anti-mouse IgG) with the right conjugate for your detection method.
• Background control: If your sample contains endogenous immunoglobulins from the same species as the host, background can increase (common in some tissue IHC workflows).
• Multiplex design: Using primaries from different host species helps avoid cross-reactivity in multi-target staining.

When to take extra care

• Mouse-on-mouse IHC/IF (mouse primary on mouse tissue) can increase background; consider mouse-on-mouse kits, highly cross-adsorbed secondaries, or alternative host species.
• For complex staining panels, use cross-adsorbed secondaries and include no-primary controls to check nonspecific binding.

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.

Agarose-conjugated antibodies are supplied pre-coupled to agarose beads, designed for immunoprecipitation (IP) and pull-down workflows. This format allows direct capture of the target from lysates without adding separate beads.

Why buyers choose agarose-conjugated antibodies

• Convenient IP setup: No separate antibody-to-bead coupling step.
• Cleaner IP: Helps reduce heavy/light chain contamination compared with eluting from Protein A/G in some workflows.
• Reliable pull-down: Useful for routine enrichment of tagged proteins and complexes.

When to consider magnetic beads instead

• If you want faster wash steps and easier handling, magnetic bead formats can be more convenient.
