Overview
This is a polyclonal anti-HLA-F antibody raised in Rabbit, conjugated with FITC. It is designed to detect HLA-F protein in Human and supports researchers working in immunology contexts where consistent antibody performance is required.
Key elements and design rationale
- Immunogen: Recombinant Human HLA class I histocompatibility antigen, alpha chain F protein (194-303AA) — the immunizing antigen determines the epitope region; confirm epitope compatibility with sample preparation and expected post-translational modifications.
- Host species (Rabbit): Requires anti-rabbit-IgG secondary reagents. Use matched secondaries to avoid no-signal or cross-reactivity issues.
- Polyclonal format: Recognizes multiple epitopes, providing robust signal across varied preparations and species variants. Inherent lot-to-lot variability requires appropriate controls.
- Isotype (IgG): Compatible with standard Protein A/G purification and widely supported by secondary reagents. Include an isotype-matched control at equivalent concentration.
- Purification (Protein G purification): Enriches for specific immunoglobulin classes, reducing non-specific populations and improving signal-to-noise.
- FITC conjugate: Direct fluorescence detection (Ex ~490/Em ~525 nm). FITC is photolabile; protect samples and use antifade reagents for slides.
Biological background
HLA-F (also referred to as CDA12, HLA 5.4, HLA class I histocompatibility antigen, alpha chain F, HLA class I molecule, HLA F antigen, HLA-CDA12, HLA-F, HLAF, HLAF_HUMAN, Leukocyte antigen F, MHC class I antigen F) is a protein target studied in Human systems. Expression levels, subcellular localization, and post-translational modifications vary across cell types, tissues, and disease states — factors that influence antibody-based detection and experimental design. Consult UniProt, NCBI Gene, and primary literature for current annotation of HLA-F biology, including known isoforms, interactors, and disease-relevant expression patterns in immunology.
Common research applications
- Refer to product documentation for confirmed application data and recommended conditions.
Notes for experimental interpretation
- Isotype controls: Use an isotype-matched (IgG from Rabbit) control at equivalent concentration to assess non-specific background.
- Cross-reactivity: Polyclonal preparations may cross-react with related proteins or isoforms. Orthogonal validation (siRNA, KO lysate, recombinant protein) is recommended to confirm signal specificity.
- Matrix effects: Sample matrix (serum, plasma, lysate, homogenate) can affect performance. Pilot dilution linearity and spike-recovery experiments are recommended for quantitative studies.
- Species reactivity: Confirmed for Human. Extrapolation to untested species requires empirical validation given potential epitope sequence divergence.
This product is a polyclonal antibody purified from rabbit antiserum.
HLA-F is a protein target in Human biology. This polyclonal antibody raised in Rabbit is designed to detect HLA-F in immunoassay applications, with IgG isotype.
This antibody is reported reactive against Human. The immunogen was derived from Human. Cross-reactivity with other species should not be assumed without documented data or empirical testing.
Application data were not specified; please consult the product datasheet or contact BioHippo support for confirmed application information.
FITC enables direct fluorescence detection (Ex ~490 nm/Em ~525 nm) without a secondary step. Protect from prolonged light exposure and use antifade mounting media for tissue sections.
Recommended: (1) Isotype control — IgG from Rabbit at matching concentration for non-specific background; (2) Positive control — known HLA-F-expressing cell/tissue; (3) Negative control — knockdown or knockout sample to confirm signal specificity; (4) Dilution linearity — verify proportional signal decrease to confirm quantitative linearity in your matrix.
