S266-KLH

S266-KLH is an immunoconjugate consisting of the synthetic small-molecule hapten S266 covalently conjugated to keyhole limpet hemocyanin (KLH), a large, highly immunogenic carrier protein derived from the sea mollusk *Megathura crenulata*. The S266-KLH conjugate is designed to elicit a strong immune response specifically against the S266 hapten, making it useful for generation of anti-S266 antibodies in research, preclinical, or clinical settings. KLH itself acts as a powerful immunostimulant, provoking both humoral and cellular immunity through mechanisms involving various immune cells such as T cells, monocytes, macrophages, and dendritic cells. This type of immunoconjugate has utility as a vaccine platform, immune system challenge agent, or as an immunogen for antibody production[1][3][4][5].
