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.
-
保存条件 & 期限
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
运输条件
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
CD21, also known as complement receptor 2 (CR2), is a critical membrane protein primarily expressed on B cells, playing a fundamental role in the modulation of the adaptive immune response. It acts as a co-receptor for the B-cell receptor (BCR), enhancing B cell activation, proliferation, and differentiation upon binding to its ligands, such as complement component C3d. The study of recombinant CD21 proteins has gained significant interest in recent years due to their potential as therapeutic agents and tools in immunology. By producing CD21 in a recombinant form, researchers can investigate its interaction with various ligands and assess its functional implications in immune responses. Furthermore, recombinant CD21 can be utilized to explore its role in diseases such as autoimmune disorders, lymphomas, and viral infections, where CD21 signaling may be dysregulated. The generation of CD21 fusion proteins allows for novel approaches in vaccine development and targeted therapies, harnessing its ability to enhance antigen presentation and stimulate B cell activity. Moreover, understanding the structural and functional properties of CD21 through recombinant technology is vital for the development of inhibitors that could modulate its activity in pathological conditions. Overall, the research surrounding recombinant CD21 holds promise for advancing our understanding of immune regulation and developing innovative therapeutic interventions in immunological diseases.
