UR-1505 is a nuclear factor of activated T cells (NF-AT) inhibitor. UR-1505 can suppress CD3/CD28 induced T cell proliferation, increase p27^KIP levels, and induce G1/S cell cycle arrest. UR-1505 can also inhibit the production of IL-5 and IFN-γ in activated T cells. UR-1505 has immunomodulatory properties and can be used in the study of atopic dermatitis.

Renvistobart is an immunoglobulin G1-κ, anti-[Homo sapiens TIGIT (T cell immunoreceptor with Ig domain and ITIM, VSIG9, VSTM3)] Homo sapiens monoclonal antibody.

Rozibafusp alfa (AMG-570) is a humanized IgG2-κ monoclonal antibody targets ICOSL and BAFF. Rozibafusp alfa can be used for the research of systemic lupus erythematosus and other autoimmune diseases.

Anti-Mouse ICOS Antibody (7E.17G9) is a mouse ICOS agonist IgG2b monoclonal antibody. Anti-Mouse ICOS Antibody (7E.17G9) can upregulate ICOS expression and enhance T cell function. Anti-Mouse ICOS Antibody (7E.17G9) can significantly inhibit the immune regulatory function of dendritic cells (DCs). Anti-Mouse ICOS Antibody (7E.17G9) can eliminate transplant tolerance. Anti-Mouse ICOS Antibody (7E.17G9) can be used for researches on inflammation conditions, cancer and xenotransplantation such as nephritis and pancreatic cancer.
