AffiniPure F(ab')₂ Fragment Goat Anti-Rabbit IgG (H+L)

(min X Hu, Ms, Rat Sr Prot)


Target: Rabbit
Host: Goat
Antibody Format: F(ab')₂ Fragment
Specificity: IgG (H+L)
Minimal Cross Reactivity: Human, Mouse, Rat Serum Proteins
Conjugate: Unconjugated
Product Category: F(ab')₂ Fragment Affinity-Purified Antibodies
Clonality: Polyclonal

Suitable for multiple labeling (see our Multiple Labeling guidance)

F(ab')2 fragment antibodies are generated by pepsin digestion of whole IgG antibodies to remove most of the Fc region while leaving some of the hinge region. F(ab')2 fragments have two antigen-binding Fab portions linked together by disulfide bonds and therefore they are divalent. The average molecular weight is about 110 kDa. They are used for specific applications, such as to avoid binding of secondary antibodies to live cells with Fc receptors or to Protein A or Protein G.

Based on immunoelectrophoresis and/or ELISA, the antibody reacts with whole molecule rabbit IgG. It also reacts with the light chains of other rabbit 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, mouse and rat serum proteins, but it may cross-react with immunoglobulins from other species.
Physical State: Sterile-filtered liquid
Storage: Store at 2-8°C under sterile conditions. Prepare working dilution fresh each day.
Expiration date: one year from date of receipt. 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.
Purity: The antibody was purified from antisera by a combination of pepsin digestion and immunoaffinity chromatography using antigens coupled to agarose beads. Fc fragments and whole IgG molecules have been removed.
Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH 7.6
Preservative: None

Suggested Working Concentration or Dilution Range:

10-20 µg / ml

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
