Invitrogen™ F(ab')2-Goat anti-Human IgG, IgM, IgA (H+L) Secondary Antibody, FITC

Description

Concentration may vary slightly from lot-to-lot, see lot-specific datasheet for exact concentration. This antibody has been successfully used in Western blot, IF, ICC, IHC, IP and FACS applications. Antibody Specificity: This antibody reacts with the heavy chains on human IgA, IgG, IgM and with light chains common to most human immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. However, this antibody may cross-react with immunoglobulins from other species. Fluorophore: Fluorescein-5-isothiocyanate (FITC-isomer 1) Amax = 492 nm; Emax = 520 nm Fluorophore/Protein: 9.9 μg/mg; 2.6 moles FITC per mole F(ab')2 Restoration and Storage: Store product at 2-8°C until opened. Restore with 0.75 mL distilled water (1.5 mg/mL after restoration). Centrifuge product if it is not completely clear after standing for 1-2 hours at room temperature. To judge clarity, draw product into a pasteur pipette. Product may be stored for several weeks at 2-8°C as undiluted liquid. After dilution, do not use for more than one day. To extend the shelf-life of this product, add an equal volume of glycerol to make a final concentration of approximately 50% glycerol and store at -20°C. Country of Origin: USA.

Anti-Human secondary antibodies are affinity-purified antibodies with well-characterized specificity for human immunoglobulins and are useful in the detection, sorting or purification of its specified target. Secondary antibodies offer increased versatility enabling users to use many detection systems (e.g. HRP, AP, fluorescence). They can also provide greater sensitivity through signal amplification as multiple secondary antibodies can bind to a single primary antibody. Most commonly, secondary antibodies are generated by immunizing the host animal with a pooled population of immunoglobulins from the target species and can be further purified and modified (i.e. immunoaffinity chromatography, antibody fragmentation, label conjugation, etc.) to generate highly specific reagents.
