简介
CD23, also known as Fc epsilon Receptor II (Fc epsilon RII), is a low-affinity receptor for immunoglobulin E (IgE) and complement receptor 2 (CR2/CD21). CD23 regulates IgE production and B-cell differentiation, aiding in IGE-dependent antigen uptake. CD23/Fc epsilon RII Protein, Rat (HEK293, Fc) is the recombinant rat-derived CD23/Fc epsilon RII protein, expressed by HEK293 , with N-hFc 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
CD23, also known as Fc epsilon RII, is a low-affinity receptor for immunoglobulin E (IgE) that plays a critical role in regulating immune responses, particularly in allergic reactions and asthma. This protein is predominantly expressed on the surface of B cells, dendritic cells, and other immune cells, serving as a key mediator in the interaction between the immune system and IgE, which is pivotal in allergy development and management. Research into CD23/Fc epsilon RII has gained significant attention due to its potential implications in understanding various allergic diseases and autoimmune disorders. Its dual role in promoting both the activation and regulation of B cell responses makes it a crucial target for therapeutic strategies aimed at modulating IgE-mediated hypersensitivity. Furthermore, the investigation of CD23's function and its interactions with other immune molecules could unlock novel avenues for immunotherapy, potentially leading to innovative treatments that alleviate allergic symptoms and enhance tolerance. The development of recombinant CD23 proteins facilitates detailed studies of its structure-function relationships, ligand interactions, and signaling pathways, paving the way for enhanced understanding of its biological significance and therapeutic potential in allergy and beyond.
