Human IgE protein (SUS-11), a highly affinity purified human IgE derived from B cells of healthy donors (no myeloma origin). It has been and is used in numerous research- and development laboratories for various in vitro and in vivo applications.
Monoclonal anti-human IgE antibody (BSW17) recognizes an epitope spanning across the C3 and C4 domains of human IgE and inhibits the binding of IgE to its high affinity receptor. Therefore, apart from classical applications (ELISA, FACS, Western Blot), BSW17 is the antibody of choice to study the mechanism of IgE dependent activation of mast cells and basophils. The properties of this monoclonal anti-human IgE Antibody have also been described in a series of international publications (see below for a selection).
Monoclonal anti-human IgE antibody (Le27) is optimally suitable for in vitro tests like ELISA, FACS, W-blot. In combination with human IgE anbtobody SUS-11 this monoclonal antibody is optimally suited for controlled mast cell activation.
A set consisting of all three components offers an ideal basis for the development of customized screening assays and ELISA for the determination of IgE concentrations in human blood samples.
These products are also available as functionally active conjugates with biotin and other standard labels (e.g. AP, FITC, PE) and can also be ordered in azide free buffer for functional tests using living cells. They are delivered with a certificate of analysis documenting purity and target binding. In case of proven quality deficiencies we guarantee take back and money refunding.
