Fab fragment antibodies are generated by papain digestion of whole IgG antibodies to remove the entire Fc portion, including the hinge region. These antibodies are monovalent, containing only a single antigen binding site. The molecular weight of Fab fragments is about 50 kDa.
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 papain 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:20-40 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.
