Recombinant PLAP Antibody / Placental Alkaline Phosphatase / N-Terminal

Overview

PLAP antibody supplied as a purified reagent for WB, IHC-P in Human samples. This product is a Recombinant rabbit monoclonal antibody (host: Rabbit; isotype: Rabbit IgG) intended for research use only. The target is commonly annotated with cytoplasmic, cell membrane localization context, which may inform staining patterns.

Key elements and design rationale

• Antibody identity: Rabbit Monoclonal; host Rabbit; isotype Rabbit IgG; clone RM317.
• Format and purification: format: Purified; purity: Protein A purified from animal origin-free supernatant.
• Species reactivity (reported): Human.
• Applications (listed): WB, IHC-P.
• Immunogen / epitope context: A peptide corresponding to the N-terminus of human placental alkaline phosphatase was used as the immunogen for the PLAP antibody..
• Localization: Cytoplasmic, cell membrane (annotation-level guidance; cell state and isoforms can shift patterns).

These attributes help you align the antibody with the biological question (target state, sample type, and readout) while keeping interpretation grounded in appropriate controls.

Biological background

PLAP is the intended antigen for this primary antibody. Reported biological context includes: Alkaline phosphatase, placental type is a membrane-bound glycosylated dimeric enzyme, also referred to as the heat-stable form, that is expressed primarily in the placenta, although it is closely related to the intestinal form of the enzyme as well as to the placental-like form.

PLAP is a tumor marker, especially in seminoma and ovarian cancer. Subcellular localization information (Cytoplasmic, cell membrane) can be useful when interpreting IF/ICC patterns and selecting compartment-enriched lysates for WB.

Research relevance and current trends

• Signal-flow and turnover studies: researchers pair immunodetection with perturbations that modulate enzymatic activity or proteostasis to understand regulation, stability, and feedback.
• Spatial and single-cell approaches: imaging-based and cytometry workflows increasingly quantify heterogeneity and relocalization rather than only bulk abundance.
• Interaction-centric biology: IP-based enrichment and proteomics are widely used to define complexes, binding partners, and context-specific interactomes.

Common research applications

• Western blot (WB): compare relative abundance/isoform patterns across conditions and sample types; band shifts may reflect processing or post-translational modification.
• IHC-P: commonly used to measure relative target levels or localization changes in the context of the experimental question.

Across these readouts, differences in signal intensity, localization, or complex enrichment are typically interpreted alongside sample-matched controls and independent evidence to distinguish regulation from technical variation.

Notes for experimental interpretation

• Isoforms, cleavage products, or post-translational modifications can alter apparent molecular weight and subcellular distribution; interpret bands and staining patterns in the context of expected biology and sample preparation.
• Species differences and epitope conservation may affect binding; use matched positive controls and orthogonal evidence when comparing across organisms.
• Control concepts: include appropriate isotype and secondary-only controls (for imaging), and consider genetic perturbations (knockout/knockdown/overexpression) or independent antibodies targeting distinct epitopes to strengthen conclusions.

Epitope context is defined by the immunogen description; when available, align this with known domains, PTM sites, or family homology to anticipate potential cross-reactivity patterns. As a monoclonal antibody, binding is driven by a single epitope, which can support consistent recognition but may be sensitive to epitope masking by PTMs or conformational changes.
