Overview
This is a polyclonal anti-CBX4 antibody raised in Rabbit, conjugated with FITC. It is designed to detect CBX4 protein in Human and supports researchers working in epigenetics and nuclear signaling contexts.
Key elements and design rationale
- Immunogen: Recombinant Human E3 SUMO-protein ligase CBX4 protein (1-160AA) — determines the epitope region; confirm compatibility with sample preparation and expected post-translational modifications.
- Host species (Rabbit): Requires anti-rabbit-IgG secondary reagents for indirect detection.
- Polyclonal format: Recognizes multiple epitopes for robust signal; inherent lot-to-lot variability requires appropriate controls.
- Isotype (IgG): Matched secondary antibodies and isotype controls required. Compatible with standard Protein A/G purification workflows.
- Purification (Protein G purification): Enriches for specific immunoglobulin classes; reduces non-specific background vs. crude antisera.
- FITC conjugate: Direct fluorescence (Ex ~490/Em ~525 nm). Protect from light; use antifade reagents for slide-based applications.
Biological background
CBX4 (also referred to as CBX 4, CBX4, Cbx4 chromobox homolog 4 (Drosophila Pc class), CBX4_HUMAN, Chromobox homolog 4 (Pc class homolog, Drosophila), Chromobox homolog 4, Chromobox protein homolog 4, E3 SUMO protein ligase CBX 4, E3 SUMO protein ligase CBX4, E3 SUMO-protein ligase CBX4, hPc 2, hPc2, NBP 16, NBP16, NS5ATP1 binding protein 16, Pc 2, Pc class 2 homolog, Pc class homolog, Pc class homolog Drosophila, PC2, Polycomb 2 homolog) is a protein target studied in Human systems. Expression, subcellular localization, and post-translational modifications vary across cell types and disease states — factors critical to antibody-based detection design. Consult UniProt, NCBI Gene, and primary literature for current annotation of CBX4 biology in epigenetics and nuclear signaling.
Common research applications
- Refer to product documentation for confirmed application data.
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. Orthogonal validation (siRNA, KO lysate) is recommended.
- Matrix effects: Sample matrix can affect performance; pilot dilution linearity and spike-recovery experiments are advised for quantitative studies.
- Species reactivity: Confirmed for Human. Extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
CBX4 is a protein target in Human biology. This polyclonal antibody raised in Rabbit is designed to detect CBX4 in immunoassay applications, with IgG isotype.
Reported reactive against Human. Immunogen derived from Human. Cross-reactivity with other species should not be assumed without documented data or empirical testing.
Application data not specified; consult the product datasheet or contact BioHippo support.
FITC direct fluorescence (Ex ~490/Em ~525 nm). Protect from light; use antifade for slide applications.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — known CBX4-expressing cell/tissue; (3) Negative control — knockdown/knockout sample for specificity; (4) Dilution linearity — verify proportional signal decrease in your matrix.
