title: Synthesis and characterization of immunogens based on calix[4]arene-crown-6 for the generation of antibodies directed towards cesium ions.
abstract: With the aim of generating antibodies directed towards cesium, a calix[4]arene-crown-6 in the 1,3-alternate conformation bearing an N-hydroxysuccinimide function was synthesized. The calixarene was coupled to bovine serum albumin using different calixarene/protein ratios, and cesium was loaded. Conjugates were characterized using trinitrobenzenesulfonic acid derivatization, matrix assisted laser desorption ionisation-mass spectrometry (MALDI-TOF-MS), and inductively coupled plasma-mass spectrometry (ICP-MS). Targeted lysines were determined after enzymatic cleavage followed by MALDI-TOF-MS, and a progressive targeting related to lysines accessibility was observed.
