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.

Protein Description
FcgR4, also known as CD16-2, is a critical receptor involved in the immune response, particularly in the recognition and elimination of pathogens by immune cells. It is predominantly expressed on natural killer (NK) cells, macrophages, and certain subsets of T cells, facilitating antibody-dependent cellular cytotoxicity (ADCC) and phagocytosis. The study of FcgR4/CD16-2 has gained attention due to its potential implications in various therapeutic areas, including cancer immunotherapy, autoimmune diseases, and infectious diseases. The receptor's ability to bind to the Fc portion of immunoglobulins enables the modulation of immune responses, making it an attractive target for designing monoclonal antibodies and enhancing their efficacy. Recent research has focused on the structural and functional characterization of recombinant FcgR4 proteins to understand their binding affinities and signaling pathways. This knowledge is crucial for developing strategies to improve antibody-mediated effector functions and to explore the therapeutic potential of engineered FcgR4/CD16-2 variants. The generation of FcgR4/CD16-2 recombinant proteins also allows for the exploration of their interactions with different classes of antibodies and other immune regulators, providing insights into the complexities of the immune system and the development of novel immunotherapies.
