Overview
Recombinant HCG-beta Antibody is a research-use primary antibody intended for detection of HCG-beta in experimental workflows. It is supplied in Purified format. Key antibody attributes include Mouse, Recombinant Mouse Monoclonal, clone rHCGb/54, isotype Mouse IgG1, kappa. Applications listed for this product include IHC-P. Reported/annotated localization context: Cytoplasmic, Secreted. Species reactivity (as provided): Human.
Key elements and design rationale
- Target: HCG-beta — selectivity and interpretation should be considered in the context of isoforms, post-translational modifications, and related family members when applicable.
- Format: Purified — format can influence background, multiplexing compatibility, and downstream detection strategies.
- Antibody identity: Mouse, Recombinant Mouse Monoclonal, clone rHCGb/54, isotype Mouse IgG1, kappa — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
- Localization: Cytoplasmic, Secreted — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
- Product notes (from provided description): This antibody reacts with a protein of 22kDa, identified as beta subunit of HCG. It does not cross react with the alpha subunit. HCG is a glycoprotein which is secreted in large quantities by normal trophoblasts. It is present only in trace amounts in non-pregnant urine and sera but rises sharply during pregnancy. HCG is composed of two non-identical, non-covalently linked polypeptide chains designated as the alpha and beta subunits. The alpha subunit is identical to that of thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), and luteinizing hormone (LH). HCG-beta antibody detects cells and tumors of trophoblastic origin such as choriocarcinoma. Large cell carcinoma and adenocarcinoma of the lung demonstrate antibody positivity in 90% and 60% of cases respectively; 20% of lung squamous cell carcinomas are positive. HCG expression by non-trophoblastic tumors may indicate aggressive behavior.
Where multiple assay formats are possible, align the antibody format, host/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.
Biological background
In this catalog, HCG-beta is positioned within Endocrinology & Hormones, Reproductive Biology, Tumor research contexts. Localization annotations (e.g., Cytoplasmic, Secreted) can help contextualize expected signal patterns in imaging and fractionation-based readouts. For authoritative gene/protein nomenclature, domains/isoforms, and curated functional annotations, consult resources such as UniProt, NCBI Gene, and Ensembl.
Research relevance and current trends
- Higher-plex and spatially resolved readouts (e.g., multiplex IF/IHC, spatial omics) are increasing demand for well-characterized primary antibodies with clearly stated host/isotype and labeling strategies.
- Genetic perturbation controls (knockout/knockdown) and orthogonal measurements (e.g., RNA vs protein) are commonly used to strengthen target attribution when interpreting antibody-derived signals.
- Reproducibility initiatives emphasize transparent reporting of antibody identity (clone, host, isotype) and experimental context to improve cross-study comparability.
Common research applications
- IHC-P: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
- Typical workflow themes: IHC on FFPE tissue, ELISA binding assay, Specificity controls.
- Workflow notes: Detect RECOMBINANTHCGB by IHC in FFPE tissue sections (optimize antigen retrieval + dilution), Measure binding to RECOMBINANTHCGB peptide/protein by ELISA with dilution series (include blanks), Confirm specificity usi…
When comparing conditions, consistent sample processing and appropriate negative/positive controls support interpretation of qualitative localization differences and quantitative abundance changes.
Notes for experimental interpretation
- Isoforms and post-translational modifications may shift apparent molecular weight or epitope accessibility, especially across cell states or treatments.
- Species and tissue context can affect sequence conservation, expression level, and background binding; predicted reactivity should be verified in your sample.
- Control concepts include isotype-matched controls, secondary-only controls (for indirect detection), and genetic/orthogonal controls (e.g., KO/KD, independent antibodies, or RNA measurements) when feasible.
Monoclonal and polyclonal antibodies can differ in epitope recognition breadth and lot-to-lot characteristics; consider clonality and clone information (when provided) alongside your assay requirements. Conjugated formats may simplify detection but can change background and multiplexing behavior compared with unconjugated primaries.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
