Beskrivelse
This brief monograph is intended chiefly for non-specialists and for others interested in a concise introduction to the field. The literature on lysosomes is growing so rapidly that any effort at exhaustive comprehensiveness would be foredoomed to failure. Fortunately, an extensive series of reviews has been published in the past few years (see especially DINGLE and FELL 1969; DINGLE 1972, 1973 a; HERS and VAN HoOF 1973) and the "history" of the organelles is brief enough that major contributors to all stages of that history are still available to provide first-hand discussions (e. g. , DE DUVE and WATTIAUX 1966; DE DUVE 1969; NOVIKOFF 1971, 1973; see also VAN FURTH for work on phago cytes and DE REUCK and CAMERON 1963 for useful reviews of early work).
