Shipping and storage
Mouse Monoclonal Antibody against Human IgE, Clone: BE5 is transported on blue ice/ice packs and should be stored at temperatures between 1 and 5 degrees Celsius. Do not freeze! Avoid exposing the product to direct light, especially the conjugated antibodies as most conjugates are very sentitive to light.

Background
Immunoglobulin E (IgE) is a 180 kDa soluble protein serving as an antigen-specific unit of mast cell effector mechanisms. IgE has the lowest serum concentration of all immunoglobulins (approximately 0.5 mg/l) in healthy individuals, but upon allergen challenge its concentration in blood increases dramatically. Although biological survival of free IgE is very short (T1/2 = 2 days), it is stabilized after binding to its high affinity receptor. Unlike IgM- IgG- and IgA-committed B cells, IgE-switched B cells do not undergo clonal expansion.

Properties
If you buy Antibodies supplied by Exbio they should be stored frozen at - 24°C for long term storage and for short term at + 5°C. Immunoglobulin E (IgE) kappa or Fc specific antibody is a kind of antibody (or immunoglobulin (Ig) "isotype") that has only been found in mammals. IgE is synthesized by plasma cells. Monomers of IgE consist of two heavy chains (ε chain) and two light chains, with the ε chain containing 4 Ig-like constant domains (Cε1-Cε4). IgEs play a role in allergy and response to parasite infection. High levels of IgEs caused by parasites can lower the allergic reaction of patients to allergens common present in the human environment. As such the parasite history of an allergic patient needs to be taken in consideration as a positive factor.

About
Monoclonals of this antigen are available in different clones. Each murine monoclonal anibody has his own affinity specific for the clone. Mouse monoclonal antibodies are purified protein A or G and can be conjugated to FITC for flow cytometry or FACS and can be of different isotypes.
