**球蛋白E(IgE)天然蛋白

Immunoglobulin E (IgE) is a class of antibody that has been found only in mammals. IgE's main function is immunity to parasites such as parasitic worms. IgE also plays an essential role in the immediate hypersensitivity states, such as asthma, hay fever, atopic dermatitis, and other well-known manifestations of atopic patients. IgE is present in normal individuals at very low concentrations, only 0.05% of the Ig concentration.

Reconstitute in sterile ddH2O.

Storage: Avoid repeated freeze/thaw cycles. Store at 2-8^oC for one month. Aliquot and store at -80^oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37^oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

Effective Size Range: 10kDa to 70kDa.
Protein bands: 10kDa, 14kDa, 18kDa, 22kDa, 26kDa, 33kDa, 44kDa and 70kDa.
Double intensity bands: The 26kDa, 18kDa, 10kDa bands are at double intensity to make location and size approximation of proteins of interest quick and easy.
Ready-to-use: No need to heat, dilute or add reducing agents before use.
