简介
IgE protein is an important immunoglobulin component that participates in the recognition and effector phases of humoral immunity. As a membrane-bound receptor on B lymphocytes, IgE triggers clonal expansion upon antigen binding, leading to plasma cell differentiation. IgE Protein, Cynomolgus (HEK293, His-Avi) is the recombinant cynomolgus-derived IgE protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
Immunoglobulin E (IgE) is a key antibody involved in allergic reactions and responses to parasitic infections. The study of IgE and its recombinant forms has gained significant attention due to the increasing prevalence of allergic diseases globally, including asthma, eczema, and food allergies. Understanding the structure and function of IgE at a molecular level is crucial for developing targeted therapies and vaccines. Recombinant IgE proteins offer the potential for studying the allergenic properties of various antigens, elucidating the mechanisms of IgE-mediated signaling, and identifying novel therapeutic targets. By engineering specific IgE variants, researchers aim to investigate their binding affinities to allergens and assess their roles in triggering mast cell activation and subsequent inflammation. Furthermore, recombinant IgE can be utilized in the development of sensitive diagnostic tools for allergy detection and in the design of immunotherapies aimed at modulating IgE responses. This research is not only pivotal for advancing allergy treatments but also contributes to broader immunological insights and the potential for innovative approaches in managing immune-related disorders.
