Jackson/AffiniPure F(ab")₂ Fragment Rabbit Anti-Sheep IgG (H+L)/1.0 mg/313-006-003
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.
Usage Physical State: Sterile-filtered liquidStorage: Store at 2-8°C under sterile conditions. Prepare working dilution on day of use. Expiration date: one year from date of receipt. The expiration date may be extended if test results are acceptable for the 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.
