Methods for preparation of live body tissues for examination

摘要

A minimally invasive procedure for perfusion-impregnation of tissues, organs and cells is provided that aids in the retention of tissue and cellular architecture without the formation of artifacts. The procedure allows for monitoring drug disposition, for detecting diseased tissue and for monitoring the presence of target molecules in a sample using various imaging techniques, including matrix assisted laser desorption ionization mass spectrometry (MALDI-MS).
