FAB and MALDI techniques, a Principle of fast-atom generation using xenon b formation of a fast-atom beam of argon in a collision chamber and bombardment of the sample MALDI. The impact of a photon leads to a similar result as with a fast atom. The mechanism for desorption ionisation is not entirely known. These ionisation modes are particularly well suited for the study of medium to high molecular weight species. They are mostly used in biomedical sciences but not for routine determinations.

FAB and MALDI techniques, MALDI or ionization by effect of illumination with a beam of laser generated light onto a matrix containing a small proportion of analyte. The impact of the photon is comparable with that of a heavy atom. Through a mechanism, as yet not fuUy elucidated, desorption and photoionization of the molecules is produced. These modes of ionization by laser firing are particularly useful for the study of high molecular weight compounds, especially in biochemistry, though not for routine measurements.

Fab antibody fragments containing free thiols can be activated with Ellman s reagent to form a sulfhydryl-reactive derivative. A-chain toxin subunits containing a free thiol group may be coupled to the activated Fab molecule to produce an immunotoxin complex.
