PHB Antibody / Prohibitin

Overview

PHB Antibody / Prohibitin is a research-use primary antibody intended for detection of PHB in experimental workflows. It is supplied in Purified format. Key antibody attributes include Rabbit, Polyclonal (rabbit origin), isotype Rabbit IgG. Applications listed for this product include WB, IHC-P, IF, Direct ELISA. Reported/annotated localization context: Cytoplasmic. Species reactivity (as provided): Human, Mouse, Rat.

Key elements and design rationale

• Target: PHB — 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: Rabbit, Polyclonal (rabbit origin), isotype Rabbit IgG — these attributes help align secondary reagents and controls (e.g., isotype-matched controls) with your assay design.
• Localization: Cytoplasmic — expected subcellular distribution can guide band/structure interpretation and help flag off-target signal.
• Product notes (from provided description): PHB (Prohibitin), also known as PHB1, is a protein that in humans is encoded by the PHB gene. White et al.(1991) mapped the PHB gene to chromosome 17 by analysis of human-mouse somatic cell hybrid cell lines using a genomic fragment of human prohibitin DNA isolated from a library using the rat prohibitin cDNA clone. By in situ hybridization, they localized the gene to 17q21. Sato et al.(1992) isolated the human homolog of the rat prohibitin gene and mapped it to 17q12-q21 by in situ hybridization. Proliferation of tumor cells depends on new blood vessel formation(angiogenesis) that accompanies malignant progression. Anticancer therapies using angiogenesis inhibitors or cytotoxic agents targeted to the vasculature of tumors have been evaluated in clinical trials. Although white fat is a nonmalignant tissue, it has the capability to quickly proliferate and expand. Furthermore, it is highly vascularized. Rupnick et al.(2002) showed that nonspecific angiogenesis inhibitors can prevent the development of obesity of mice.

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, PHB is positioned within Molecular & Cellular Biology, Cancer, Tumor, Obesity research contexts. Localization annotations (e.g., Cytoplasmic) 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

• WB: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IHC-P: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• IF: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• Direct ELISA: interpret changes in signal in the context of sample composition, epitope accessibility, and potential isoform/PTM differences across conditions.
• Typical workflow themes: Western blot validation, IHC on FFPE tissue, IF/ICC localization, ELISA binding assay, Specificity controls.
• Workflow notes: Validate PROHIBITIN by Western blot in cell/tissue lysates (include controls), Detect PROHIBITIN by IHC in FFPE tissue sections (optimize antigen retrieval + dilution), Detect PROHIBITIN localization by IF/ICC in cult…

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).
