Overview
This is a polyclonal anti-IL13RA1 antibody raised in Rabbit, conjugated with HRP, with confirmed utility in ELISA. It is designed to detect IL13RA1 protein in Human and supports researchers working in immunology contexts.
Key elements and design rationale
- Immunogen: Recombinant Human Interleukin-13 receptor subunit alpha-1 protein (22-234AA) — 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 (Antigen affinity purification): Enriches for specific immunoglobulin classes; reduces non-specific background vs. crude antisera.
- HRP conjugate: Direct detection with TMB/OPD or ECL substrates. Quench endogenous peroxidase before use in tissue assays.
Biological background
IL13RA1 (also referred to as bB128O4.2.1 (interleukin 13 receptor, alpha 1), Cancer/testis antigen 19, CD213a1, CD213A1 Antigen, CT 19, CT19, I13R1_HUMAN, IL 13 receptor subunit alpha 1, IL 13R alpha 1, IL 13R subunit alpha 1, IL 13Ra , IL 13RA1, IL-13 receptor subunit alpha-1, IL-13R subunit alpha-1, IL-13R-alpha-1, IL-13RA1, IL13 receptor alpha 1 chain, IL13R , IL13RA , Il13ra1, Interleukin 13 receptor alpha 1 , Interleukin 13 receptor alpha 1 chain, interleukin 13 receptor subunit alpha 1, Interleukin-13 receptor subunit alpha-1, NR 4, NR4) 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 IL13RA1 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.
IL13RA1 is a protein target in Human biology. This polyclonal antibody raised in Rabbit is designed to detect IL13RA1 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.
HRP enables direct TMB/ECL detection without secondary. Quench endogenous peroxidase in tissue assays.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — known IL13RA1-expressing cell/tissue; (3) Negative control — knockdown/knockout sample for specificity; (4) Dilution linearity — verify proportional signal decrease in your matrix.
