Overview
This is a polyclonal anti-ITGA2 antibody raised in Rabbit, with confirmed utility in ELISA, IHC, IF. Designed to detect ITGA2 in Human, supporting researchers in signal transduction contexts.
Key elements and design rationale
- Immunogen: Recombinant Human Integrin alpha-2 protein (188-365AA) — determines the epitope region recognized; confirm epitope compatibility with your sample preparation and expected PTMs.
- Host (Rabbit): Requires anti-rabbit-IgG secondary reagents. Mismatched secondaries result in no signal. Consider host species when multiplexing.
- Polyclonal: Recognizes multiple epitopes — robust signal across varied preparations, with inherent lot-to-lot variability. Isotype controls and lot qualification recommended.
- Isotype (IgG): Secondary antibodies and isotype controls must match IgG from Rabbit. Relevant for multiplexing and Protein A/G compatibility.
- Purification (Protein G purification): Reduces non-specific immunoglobulin populations, improving signal-to-noise in quantitative immunoassay formats.
Biological background
ITGA2 (also known as BR, CD 49b, CD49 antigen like family member B, CD49 antigen-like family member B, CD49b, CD49b antigen, Collagen receptor, DX5, Glycoprotein Ia deficiency included, GP Ia, GP Ia deficiency, included, GPIa, HPA 5 included, HPA5 included, Human platelet alloantigen system 5, Integrin alpha 2, Integrin alpha II, Integrin alpha-2, Integrin, alpha 2 (CD49B alpha 2 subunit of VLA 2 receptor), ITA2_HUMAN, ITGA2, Platelet alloantigen Br(a), included, Platelet antigen Br, Platelet glycoprotein GPIa, Platelet glycoprotein Ia, Platelet glycoprotein Ia/IIa, Platelet membrane glycoprotein Ia, Platelet receptor for collagen, deficiency of, included, Very late activation protein 2 receptor alpha 2 subunit, VLA 2 alpha chain, VLA 2, VLA 2 subunit alpha, VLA-2 subunit alpha, VLA2, VLA2 receptor alpha 2 subunit, VLAA2) is a protein 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 outcomes. Researchers are encouraged to consult UniProt, NCBI Gene, and primary literature for current annotation of ITGA2 biology relevant to signal transduction.
Common research applications
- ELISA: Sandwich or indirect ELISA quantifies soluble/secreted target in biological fluids or cell culture supernatants.
- IHC: IHC visualizes target expression in FFPE or frozen sections; optimize antigen retrieval and secondary detection per tissue type.
- IF: IF localizes target at subcellular resolution in fixed cells/sections; fixation and permeabilization conditions affect epitope accessibility.
Notes for experimental interpretation
- Isotype controls: Include IgG from Rabbit at equivalent concentration to assess non-specific background.
- Cross-reactivity/isoforms: Polyclonal preparations may cross-react with related proteins or isoforms — validate with siRNA KD, KO lysate, or recombinant protein controls.
- Matrix effects: Sample matrix (serum, plasma, lysate, homogenate) may influence performance; pilot dilution linearity and spike-recovery experiments before full quantitative studies.
- Species reactivity: Confirmed for Human; extrapolation to untested species requires empirical validation.
This product is a polyclonal antibody purified from rabbit antiserum.
ITGA2 is a protein target in Human biology. This polyclonal antibody raised in Rabbit detects ITGA2 and is validated for ELISA, IHC, IF applications.
This antibody is reported reactive against Human. Immunogen derived from Human. Cross-reactivity with unlisted species should not be assumed — contact us or consult the datasheet for homology data.
Supplier reports performance in ELISA, IHC, IF. Dilution optimization, blocking, and appropriate controls are required per format. Contact BioHippo for recommended working concentrations.
This non-conjugated (IgG) antibody requires a secondary anti-rabbit IgG conjugated to HRP, AP, fluorophore, or biotin. Match the secondary to the host (Rabbit) and isotype (IgG).
(1) Isotype control — IgG from Rabbit at matching concentration; (2) Positive control — lysate/cell line expressing ITGA2; (3) Negative control — siRNA KD or KO sample to confirm specificity; (4) Dilution linearity — verify proportional signal decrease for quantitative applications.
