Chèvre anti-Rat IgG2b Anticorps (TRITC)

N° du produit ABIN1099730

Détail du produit

Antigène: IgG2b

Reactivité: Rat

Hôte: Chèvre

Clonalité: Polyclonal

Conjugué: TRITC

Application: ELISA, Immunohistochemistry (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC)

Specificité: The reactivity of the antiserum is directed to the subclass IgG2b.

Attributs du produit: Physicochemical characteristics: IgG protein concentration 10 mg/mL. Fluorochrome/IgG protein molar ratio (F/P) is approximately 1.8.

Physical form: TRITC-coupled purified hyperimmune goat IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2).

Fluorescent marker: Tetramethylrhodamine isothiocyanate isomer R. It has an orange-red fluorescence.
Excitation: 554 nm, emission: 573 nm. To avoid nonspecific background staining, specially synthesized and exceptionally pure crystalline isomer R has been used instead of the usual racemic mixture. Although its fluorescence efficiency is less than of FITC, TRITC conjugates have the advantage of significantly less photo bleaching. This facilitates their use in quantitative cell-counting procedures.

Conjugation procedure: A proprietary technique for the binding of TRITC is used, followed by several purification steps to remove free reactants and protein aggregates. After each step activity and specificity are tested in a variety of techniques. The conjugate is lyophilized to assure stability and long shelf life.

Purification: Hyperimmune antisera with strong precipitating activity are selected for fractionation and purification of the IgG (7S) fraction containing the bulk of the defined antibody specificity. It is free of other serum proteins as tested by immunoelectrophoresis.
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.

Immunogène: Pools of purified homogenous IgG2b isolated from rat serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Information d'application

Indications d'application: Working dilutions are usually between 1:10 and 1:60, depending on the method used.

Restrictions: For Research Use only

Stockage

Format: Lyophilized

Reconstitution: It is reconstituted by adding 1 mL sterile distilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20 °C.

Buffer: Phosphate buffered saline (PBS, pH 7.2)

Agent conservateur: Without preservative

Conseil sur la manipulation: Prior to use, an aliquot is thawed slowly at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +0 °C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the immunoconjugate.

Stock: 4 °C/-20 °C

Stockage commentaire: The lyophilized conjugate is shipped at ambient temperature and may be stored at +4 °C, prolonged storage at or below -24 °C.

Détail du antigène

Antigène: IgG2b

Abstract: IgG2b Produits

Classe de substances: Antibody

Sujet: In 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 identify and 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.
