Overview
This is a polyclonal anti-PLA2G4B antibody raised in Rabbit, conjugated with Biotin, with confirmed utility in ELISA. It is designed to detect PLA2G4B protein in Human and supports researchers working in immunology contexts.
Key elements and design rationale
- Immunogen: Recombinant Human Cytosolic phospholipase A2 beta protein (514-781AA) — 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.
- Biotin conjugate: Amplified detection via streptavidin/avidin reporters. Block endogenous biotin in biotin-rich tissue samples.
Biological background
PLA2G4B (also referred to as PLA2G4B, Cytosolic phospholipase A2 beta, cPLA2-beta, EC 3.1.1.4, Phospholipase A2 group IVB) 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 PLA2G4B biology in immunology.
Common research applications
- ELISA: Quantification of soluble target in biological fluids or culture supernatants. Ensure samples are within the linear detection range.
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.
PLA2G4B is a protein target in Human biology. This polyclonal antibody raised in Rabbit is designed to detect PLA2G4B in ELISA 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.
Reported for ELISA. Each format requires independent dilution optimization and appropriate controls. Unlisted applications require empirical testing.
Biotin enables streptavidin/avidin-amplified detection. Block endogenous biotin in biotin-rich tissues.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — known PLA2G4B-expressing cell/tissue; (3) Negative control — knockdown/knockout sample for specificity; (4) Dilution linearity — verify proportional signal decrease in your matrix.
