KRN7000 is a synthetic analog of α-galactosylceramide and the marine natural product agelasphin. It is a specific ligand for human and mouse NKT cells and remains the best studied ligand of the lipid-binding MHC class I-like protein CD1d. KRN7000 protects against LPS-induced shock and displays potent antitumor activity in various in vivo models.

Formulation for dissolving KRN7000:
 
Using pyrogen-free water, a solution is made of sucrose (57 mg/mL), L-histidine (7.5 mg/mL), and Tween 20 (5 mg/mL). The pH is adjusted to 7.2. KRN7000 is dissolved in a 10:1 (vol:vol) mixture of THF and methanol at a concentration of 1 mg/mL.  The KRN7000 solution is added dropwise to the aqueous solution with constant stirring (20 µL KRN7000 solution per mL of aqueous solution).  The resulting mixture is sonicated in a bath sonicator for 10 min and filter-sterilized.
