Opis

The technique of needle microinjection has become a prominent experime ntal approach in biological research. Cellular organelles, DNA and RNA, enzymes, structural proteins, metabolites, ions and antibodies are j ust some of the molecular and cellular elements that have been transpo sed from test tubes into living cells by needle injection. This techni que is broadly used as a valuable tool for the study of many different cell responses in a variety of systems. From individual cell signalin g responses, such as regulation of metabolic pathways and second funct ion of second messengers, the fate of injected proteins in cellular co mpartments and cytoskeletal regulation, to the definition of apoptosis and survival signals and transformation of whole organisms such as ne matodes. This book presents information on the techniqueFs principles, the required equipment, preparation of receiving cells and injected material and the analysis of the results.
