<p>Method for determining endotoxins in a liquid, wherein said liquid is contacted, at 20?oC - 40o¿C, with a lysate of limule amebocytes and an aqueous solution of a peptide having the following formula$(7,)$wherein ¨ADPept¨BD is a peptidic hydrophobic chain, n is 1, 2, 3, 4 or 5, B is$(5,)$R¿1?, R2 and R3 being H or CH3, ¨ADNH-Ar¨BD is the residue of a fluorescent heteroaromatic amine and X?O¿ is an anion, the pH of the thus obtained medium is adjusted at 5 to 10 and the heteroaromatic amine thus formed is determined; and new peptides according to formula (I) usable in said method.</p> |
