Overview
This is a polyclonal anti-GAG antibody raised in Rabbit, with confirmed utility in ELISA, WB. It is designed to detect GAG protein in Avian leukosis virus RSA and supports researchers working in others contexts.
Key elements and design rationale
- Immunogen: Recombinant Avian leukosis virus RSA (RSV-SRA) (Rous sarcoma virus (strain Schmidt-Ruppin A)) GAG protein (489-577aa) — 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.
Biological background
GAG (also referred to as Gag-Pro polyprotein [Cleaved into: Matrix protein p19, p2A, p2B, p10, Capsid protein p27, alternate cleaved 1, Capsid protein p27, alternate cleaved 2, Spacer peptide (SP) (p3), Nucleocapsid protein p12, Protease p15 (EC 3.4.23.-)] gag-pro) is a protein target studied in Avian leukosis virus RSA (RSV-SRA) (Rous sarcoma virus (strain Schmidt-Ruppin A)) 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 GAG biology in others.
Common research applications
- ELISA: Quantification of soluble target in biological fluids or culture supernatants. Ensure samples are within the linear detection range.
- WB: Confirms target molecular weight and distinguishes isoforms under denaturing 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. 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 Avian leukosis virus RSA. Extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
GAG is a protein target in Avian leukosis virus RSA biology. This polyclonal antibody raised in Rabbit is designed to detect GAG in ELISA, WB applications, with IgG isotype.
Reported reactive against Avian leukosis virus RSA. Immunogen derived from Avian leukosis virus RSA (RSV-SRA) (Rous sarcoma virus (strain Schmidt-Ruppin A)). Cross-reactivity with other species should not be assumed without documented data or empirical testing.
Reported for ELISA, WB. Each format requires independent dilution optimization and appropriate controls. Unlisted applications require empirical testing.
This non-conjugated IgG antibody requires a compatible secondary. Select anti-rabbit IgG secondary conjugated to your preferred reporter (HRP, AP, fluorophore, or biotin), matched to IgG.
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — known GAG-expressing cell/tissue; (3) Negative control — knockdown/knockout sample for specificity; (4) Dilution linearity — verify proportional signal decrease in your matrix.
