Rabbit IgA (Fc specific) Goat Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, ID, IF, IHC, IP, WB
Recommended Dilution	In immunocytochemical and immunohistochemical staining of IgA at the cellular and subcellular level of appropriately treated cell and tissue substrates; to demonstrate circulating IgA antibodies in serodiagnostic microbiology and autoimmune diseases; to identify a specific antigen using a reference antibody of rabbit origin known to be of the IgA isotype in the middle layer of the indirect test procedure. Antisera to IgA do not discriminate between serum IgA (monomeric and dimeric) and higher molecular forms such as secretory IgA. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Recommended working dilutions: 1/20 - 1/80.
Reactivities	Rabbit
Host	Goat
Isotype	IgG
Clonality	Polyclonal
Immunogen	Pools of purified IgA isolated from rabbit serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Specificity	The reactivity of the antiserum is directed to the Fc subunit of the IgA molecule, which expresses strict (class) specificity. In immunoelectrophoresis and radial in immunodiffusion using various antiserum concentrations against rabbit serum, a single precipitin line has been obtained which shows a reaction of identity with the precipitin lines obtained with the purified IgA used as immunogens. It does not react with IgG, IgG/Fab fragments and IgM or any non-Ig protein in rabbit serum, as tested by immunoelectrophoresis and double radial immunodiffusion. Cross-reactivity: This immunoconjugate is not species-specific since inter-species cross-reactivity is a normal feature of antisera to immunoglobulins. Cross-reactivity of this antiserum has not been tested in detail.
Formulation	PBS, pH 7.2 without preservatives and foreign proteins Label: FITC State: Lyophilized purified IgG fraction Label: Fluorescein Isothiocyanate Absorption emission: 492 nm / 515 nm Molar radio: Fluorochrome/IgG: ~1.6
Reconstitution Method	Restore by adding 0.5 ml sterile distilled water.
Concentration	10,0 mg/ml
Purification	Immunoaffinity Chromatography
Conjugation	FITC
Storage	Prior to and following reconstitution store the antibody at 2-8°C for one month or at -20°C for longer. Avoid repeated freezing and thawing.
Note	Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibodies cross-reacting with other components of the immunoglobulin system or reacting with other serum proteins. Special attention is given to the removal of antibodies to common Ig/Fab. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
