Clone Host Grade Applications
Polyclonal Sheep Serum E
Tested in immunoelectrophoresis, double radial immunodiffusion and ELISA against a panel of appropriate secretions and purified Ig isotypes. The antiserum reacts with both bound secretory component (secretory IgA) and with the free SC present in human secretions. In immunoelectrophoresis against human milk, using a high electroendosmosis agar plate, free SC is precipitated in the alpha-2 region. The antiserum does not react with other molecular forms of IgA, or with any other secretory or plasma protein. In precipitating techniques as immunoelectrophoresis and single and double radial immunodiffusion to identify the presence secretory component in human serum or other body fluids and to determine its concentration.
Catalog #I1890-31D
ApplicationsSuitable for use in ELISA, Immunoelectrophoresis and Double Radial Immunodiffusion. Other applications not tested.
Recommended DilutionImmunoelectrophoresis: 2ul plasma or equivalent against 120ul antiserum
Double Radial Immunodiffusion: Use a rosette arrangement with 10ul antiserum in 3mm
diameter center well and 2ul plasma samples (neat and serially diluted) in 2mm diameter
peripheral wells.
Optimal dilutions to be determined by the researcher.
