Anti-SMTN antibody (700-800) [PTR1305] (STJA0006269)

What it means: Monoclonal antibodies originate from a single hybridoma clone that recognizes one defined epitope on the target antigen — making Monoclonal antibodies uniquely consistent between lots.

Why it matters:

• Monoclonal antibodies offer lot-to-lot reproducibility that is critical for longitudinal studies, quantitative assays, and any experimental design requiring matched performance across timepoints or collaborating labs.
• The defined single-epitope binding profile enables reliable pairing with a non-competing capture antibody for sandwich ELISA, proximity ligation, and flow cytometry multiplex panels.

How to interpret here: A single, well-optimized titration for this Monoclonal antibody transfers reliably across experiments. Confirm whether the target epitope is preserved under your fixation or denaturation conditions before proceeding with IHC or WB applications.

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: This antibody has validated reactivity to Human antigen, confirming it binds the Human ortholog of the target protein in immunoassay conditions.

Why it matters:

• Reactivity to Human is confirmed through experimental validation — not merely predicted from sequence homology — ensuring reliable performance in Human-derived samples such as cell lysates, tissues, or serum.
• Use of this antibody with non-Human samples requires independent validation; predicted cross-reactivity should always be confirmed empirically.

How to interpret here: Ensure your experimental samples are of Human origin. If you require reactivity to additional species, contact our team to identify a cross-reactive alternative.

What it means: Unconjugated format means no detection label is attached to this antibody — you supply a compatible secondary antibody or detection reagent of your choice.

Why it matters:

• The Unconjugated format gives maximum flexibility: pair with HRP-, fluorochrome-, or biotin-conjugated secondary antibodies matched to your detection platform, enabling use across WB, IHC, IF, and ELISA without ordering separate conjugated primary formats.
• Signal amplification is possible by using a biotinylated secondary followed by a streptavidin-enzyme conjugate, which is not available with directly conjugated primary antibodies.

How to interpret here: Select an anti-host-species secondary antibody conjugated to your preferred detection label. For most indirect detection workflows, the Unconjugated primary antibody is the recommended starting format.

What it means: IgG2ak is the immunoglobulin class and subclass of this antibody, defining its constant-region structure and effector functions.

Why it matters:

• Isotype IgG2ak 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 (IgG2ak) 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 IgG2ak signal independently.

What it means: The antibody was affinity-purified from rabbit serum by affinity-chromatography using specific immunogen. indicates the chromatographic method used to isolate this antibody from the production matrix, ensuring a defined purity level.

Why it matters:

• The antibody was affinity-purified from rabbit serum by affinity-chromatography using specific immunogen. removes bulk serum proteins that could cause non-specific binding or elevated background in downstream assays — a critical quality attribute for immunoassay performance.
• The The antibody was affinity-purified from rabbit serum by affinity-chromatography using specific immunogen. process is routinely validated and documented by the manufacturer as part of QC release, providing traceability for GLP-adjacent studies.

How to interpret here: Confirm the purity specification on the Certificate of Analysis. For the most demanding applications (single-cell IF, proximity ligation), The antibody was affinity-purified from rabbit serum by affinity-chromatography using specific immunogen. purity is the recommended minimum standard.

What it means: PTR1305 is the unique clone designation of this monoclonal antibody, identifying the specific hybridoma lineage that defines its epitope and performance characteristics.

Why it matters:

• Clone PTR1305 allows precise cross-referencing with published literature — if peer-reviewed studies cite this specific clone, its performance in your assay context is already independently validated.
• Recording clone PTR1305 in your methods section enables collaborators and reviewers to replicate your exact reagent, satisfying increasingly stringent journal antibody reporting requirements (RRID registration, clone number disclosure).

How to interpret here: Search clone PTR1305 in published literature and antibody validation databases to review independent performance data. Always record the full clone designation in experimental notes for complete reproducibility documentation.
