CAT#: AP21491HR-N

Rat IgG2b (subclass specific) goat polyclonal antibody, HRP

Specifications

Product Data

• Applications: ELISA, ID, IF, IHC, IP, WB
• Recommended Dilution: Can be used in Enzyme-Immunocytochemical and Immunohistochemical staining for the detection of IgG2b at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates, to demonstrate circulating IgG2b antibodies in serodiagnostic microbiology and autoimmune diseases, to identify a specific antigen using a reference antibody of rat origin known to be of the IgG2b isotype in the middle layer of the indirect test procedure, in non-isotopic assay methodology (e.g. ELISA) to measure IgG2b in Rat serum or other body fluids.
  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:
  Histochemical and Cytochemical Use: 1/50-1/250.
  ELISA and comparable non-precipitating antibody-binding assays: 1/1000-1/10000.
• Reactivities: Rat
• Host: Goat
• Isotype: IgG
• Clonality: Polyclonal
• Immunogen: Pools of purified homogenous IgG2b isolated from Rat sera.
  Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Specificity: The reactivity of the antiserum is directed to the subclass IgG2b. It does not react with other subclasses of IgG, IgG/Fab fragments, IgM and IgA or any non-Ig protein in rat serum, as tested by Immunoelectrophoresis and Double Radial Immunodiffusion and more sensitive techniques.
  Cross-reactivity: This immunoconjugate is not species-specific since inter-species cross-reactivity is a normal feature of antisera to immunoglobulins. Cross-reactivity has not been tested in detail.
• Formulation: PBS, pH 7.2 without preservatives and foreign proteins
  Label: HRP
  State: Lyophilized purified IgG fraction
  Label: Horseradish Peroxidase
  Molar radio: Peroxidase/IgG: ~1.7
• Reconstitution Method: Restore by adding 1.0 ml sterile distilled water
• Concentration: 10 mg/ml
• Purification: Immunoaffinity Chromatography
• Conjugation: HRP
• 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.
