We have created the Penn State Protein Ladder system to produce protein molecular weight markers easily and inexpensively (less than a penny a lane). The system includes plasmids which express 10, 15, 20, 30, 40, 50, 60, 80 and 100 kD proteins inE. coli. Each protein migrates appropriate...
In order to develop a practical chip for diagnostic tests, anti-C-reactive protein antibody was continuously ejected using a piezoelectric injector and microdeposition was monitored on a shot-by-shot basis using a 30MHz quartz crystal microbalance. Background noise due to external sources such as ...
