  Facile synthesis of biotin-labelled α-galactosylceramide as antigen for invariant natural killer T cells

  摘要：

  When iNKT cells are stimulated by the CD1d presented exogenous alpha-galactosylceramide, a myriad of cytokines are released that trigger a variety of immune responses. However, the invisibility and poor aqueous Solubility of alpha-galactosylceramide during bioassays have rendered it difficult to study the aforementioned biological responses. Accordingly, a biotin-labelled alpha-galactosylceramide was prepared to facilitate detection of this antigen in the immune process. The problematic low solubility was also remedies via incorporation of a truncated acyl chain. (C) 2009 Elsevier Ltd. All rights reserved.
