Goat polyclonal antibody against human IgA, affinity-purified on immobilised human IgA and cross-adsorbed against human IgG and IgM, 1 mg. IgA-specific (a-chain) — no reactivity to human IgG, IgM or other serum proteins. Unconjugated liquid (glycerol) format for isotype-specific human-IgA ELISA, Western blot, immunohistology and custom conjugation — the single-isotype complement to the pan-class cat. 172 (rabbit anti-human IgG + IgM + IgA).
SPECIFICATIONS
Catalogue number: 315 | Host: Goat | Target: Human
Target antigen: Human IgA (a-chain)
Reactivity: Human IgA
Clonality: Polyclonal | Conjugate: Unconjugated
Specificity: Human IgA-specific; no reactivity to human IgG, IgM or other serum proteins (cross-adsorbed).
Purification: Affinity chromatography on immobilised human IgA, cross-adsorbed against human IgG and IgM.
Format: Liquid, 1 mg/mL in 0.01 M sodium phosphate pH 7.5, 0.1 M NaCl, 50 % glycerol | Package size: 1 mg
STORAGE
Ships at ambient temperature. Store at -20 °C; the 50 % glycerol keeps the antibody liquid at -20 °C, so there are no freeze-thaw concerns. Avoid microbial contamination.
APPLICATIONS
- ELISA — isotype-specific human-IgA detection or capture (1:1 000).
- Western blot — detection of the human IgA a-chain.
- Immunohistology — IgA-plasma-cell and mucosal-IgA detection.
- Custom conjugation — glycerol / phosphate liquid format compatible with HRP / biotin / fluorophore labelling.
APPLICATION HIGHLIGHTS — HIGH-VALUE RESEARCH NICHES
- Mucosal immunology — secretory-IgA quantification.
- IgA nephropathy research — IgA-deposition detection.
- Isotype-specific serology — IgA-class antibody titres (vaccine / infection).
- Plasma-cell / B-cell isotype profiling.
