简介
LILRB3/CD85a protein, as a receptor for class I MHC antigens, plays an indispensable role in immune recognition. Activation of LILRB3 occurs through binding to immune receptors such as FCGR2B and B cell receptors, resulting in downregulation of antigen-induced B cell activation. LILRB3/CD85a Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived LILRB3/CD85a protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Stability Test
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.
-
Storage & Shelf Life

Protein Description
LILRB3, also known as CD85a, is a member of the leukocyte immunoglobulin-like receptors (LILR) family, which play a crucial role in modulating immune responses. The significance of LILRB3 lies in its ability to interact with major histocompatibility complex (MHC) class I molecules, thereby influencing the activity of various immune cells, including T cells and natural killer (NK) cells. Research into LILRB3/CD85a has gained momentum due to its potential implications in immunology and therapeutic interventions, particularly in cancer, autoimmune diseases, and transplant rejection. The expression of LILRB3 on immune cells often correlates with immune evasion mechanisms employed by tumors, making it a target of interest for developing novel immunotherapeutic strategies. Additionally, the study of LILRB3/CD85a recombinant proteins facilitates a deeper understanding of its structure-function relationships, signaling pathways, and interactions with other immune regulators. As researchers explore the modulation of LILRB3 activity, the development of recombinant proteins can serve as valuable tools for elucidating its biological roles and assessing its therapeutic potential in enhancing anti-tumor immunity or restoring immune tolerance in various clinical contexts.
