Mouse anti Sheep IgE, clone 1E7, recognizes ovine Immunoglobulin E (IgE) and does not cross react with ovine IgM, IgA, IgG1 or IgG2.

IgE is an immunoglobulin primarily produced from plasma cells and, in normal serum, present at very low concentrations. Western blot analysis against affinity purified ovine IgE using Mouse anti Sheep IgE clone 1E7 demonstrates a single major band of approximately 80 kDa under reducing conditions, and a band at approximately 200 kDa is observed after electrophoresis under non-reducing conditions. These bands correspond with the expected molecular weights of the epsilon chain and the complete ovine IgE molecule (Kooyman, F.N. et al. 1997).

IgE is in important in both type 1 hypersensitivity and immunity to parasite infections, in particular parasitic worm infections. Mouse anti Sheep IgE, clone 1E7 has been used in a number of studies involving parasite nematode infections of sheep by Haemonchus contortus (Vervelde, L. et al. 1997 and Kooyman, F.N. et al. 1997). Clone 1E7 also recognizes bovine IgE, and as such it is useful for studies of infection in cattle by nematode worms such as Dictyocaulus viviparus (Bricarello, P.A. et al. 2007 and Kooyman, F.N. et al. 2002).

In addition to this specific anti IgE monoclonal antibody, monoclonal antibodies specific to both bovine and ovine, IgA, IgM and IgG subclasses are available from Bio-Rad.
