Human anti-SEB mAb (IgG121)

What it means: Clonality describes how this antibody was generated and how it recognises its antigen. A Monoclonal antibody is produced from a single B-cell clone and binds one precisely defined epitope.

Why it matters:

• A Monoclonal reagent has a characteristic balance of signal strength, specificity and lot-to-lot consistency that shapes how it performs in an assay.
• Polyclonal antibodies amplify total signal and tolerate minor epitope variation or partial denaturation, which suits detection assays such as ELISA and Western blot.
• Monoclonal antibodies deliver defined, highly reproducible specificity and are preferred where a single epitope and tight lot consistency are required.

How to interpret here: This product is supplied as a Monoclonal antibody, so design your experiment around the binding behaviour and specificity profile described above for a Monoclonal reagent.

Tip: In a sandwich format, pairing a polyclonal capture antibody with a monoclonal detector often gives the best sensitivity and specificity.

What it means: The host is the species in which this antibody was raised. This antibody was generated in a Human host, which determines the secondary-detection reagents it is compatible with.

Why it matters:

• The Human host species dictates that you use an anti-Human secondary antibody for indirect detection.
• Host species is critical when multiplexing: two primary antibodies from the same host cannot be distinguished by species-specific secondaries.
• It also affects background — the secondary must not cross-react with the sample species or with other primaries in the panel.

How to interpret here: Because the host is Human, select an anti-Human conjugated secondary antibody and confirm it does not cross-react with your sample species or co-stained targets.

Tip: When building a multiplex panel, choose primary antibodies raised in different host species to keep detection clean.

What it means: Isotype identifies the immunoglobulin class and subclass of this antibody. This antibody is of the IgG1 isotype, which influences detection and control choices.

Why it matters:

• The IgG1 isotype guides selection of isotype-specific secondary antibodies and of capture or purification reagents.
• It defines the matching isotype control needed to establish background in flow cytometry and cell-based assays.
• Isotype can also affect effector behaviour in functional assays, so it should be recorded in your methods.

How to interpret here: This antibody is IgG1; match your secondary reagents and isotype control antibody to the IgG1 subclass for valid results.

Tip: Always include an isotype-matched control antibody when quantifying specific staining.

What it means: The target pathogen is the infectious agent whose antigen this antibody is designed to detect — Staphylococcal enterotoxin B (SEB) virus.

Why it matters:

• Matching the antibody to the correct Staphylococcal enterotoxin B (SEB) virus antigen is essential for specific, interpretable detection.
• Pathogen and strain context determine suitability for serology, assay development, surveillance and outbreak research.
• Closely related species or strains can share epitopes, so cross-reactivity should be considered in panel design.

How to interpret here: This antibody is directed against Staphylococcal enterotoxin B (SEB) virus (Staphylococcus Aureus USA300 strain); confirm it matches the pathogen and strain used in your study before relying on the signal.

Tip: Validate cross-reactivity in-house if your work involves related Staphylococcal enterotoxin B (SEB) virus species.

What it means: Applications lists the laboratory techniques for which the manufacturer has characterised this antibody: ELISA, Western Blot.

Why it matters:

• Using the antibody within a characterised application (ELISA, Western Blot) reduces optimisation time and the risk of artefacts.
• Each application still requires titration in your own samples and instrument to find the optimal working dilution.
• Applications not listed here should be treated as user-validated and confirmed with appropriate controls.

How to interpret here: This antibody is characterised for ELISA, Western Blot; treat any other technique as a user-validated application requiring in-house verification.

Tip: Run a positive and a negative control alongside test samples when establishing a new application.

What it means: Storage gives the recommended conditions for maintaining product stability and performance: Store at +4°C for 2-3 weeks, ≤-20°C for long term.

Why it matters:

• Following the storage guidance preserves the activity and integrity of the product over its usable life.
• Improper storage or repeated freeze-thaw cycling is a common, avoidable cause of inconsistent results.
• Correct storage protects the reagent across multiple experiments.

How to interpret here: Store this product exactly as stated (Store at +4°C for 2-3 weeks, ≤-20°C for long term) from receipt.

Tip: Aliquot on arrival to minimise freeze-thaw cycles.
