Brilliant Violet™ 421-AffiniPure Goat Anti-Mouse IgG, Fc? Subclass 2a Specific (min X Hu,Bov,Rb Sr Prot)

Whole IgG antibodies are isolated as intact molecules from antisera by immunoaffinity chromatography. They have an Fc portion and two antigen binding Fab portions joined together by disulfide bonds and therefore they are divalent. The average molecular weight is reported to be about 160 kDa. The whole IgG form of antibodies is suitable for the majority of immunodetection procedures and is the most cost effective.Based on antigen-binding assay and/or ELISA, the antibody reacts with the Fc portion of mouse IgG2a but not with other mouse IgG subclasses, mouse IgM, or the Fab portion of mouse immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with human, bovine and rabbit serum proteins, but it may cross-react with immunoglobulins from other species.

• Clonality: Polyclonal
• Host: Goat
• Reactivity: Mouse

• Quantity: 0.25 ml
• Storage: Store freeze-dried powder at 2-8°C. When ready to use, rehydrate with indicated volume of d. water and centrifuge if not clear. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid. Prepare working dilution fresh each day. For extended storage after rehydration, add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid. Note: after the addition of glycerol, the concentration of protein and buffer salts is one-half of the original. Alternatively, aliquot and freeze the product at -70°C or below in the absence of glycerol. Avoid repeated freezing and thawing. Expiration date: one year from date of rehydration. However, the expiration date may be extended if the product is stored according to the recommendation and the test results are acceptable for its intended use. Note: Store stained specimens at 4°C to preserve fluorescence.
• Buffer: 0.01M Sodium Phosphate, 0.15M NaCl, 0.005% Tween 20, pH 7.2
