A multi-institution effort has resulted in a paper that details how antigen-coated membrane vesicles derived from the surface of E. coli cells protected mice from a deadly pathogen, and how that system could work against other pathogens, as well.
By using Fourier Transform Infrared Spectroscopy (FTIR), researchers can greatly increase the amount of information that can be extracted from a protein microarray. They show how high-quality spectra can be obtained from spots of protein no larger than the diameter of a human hair.
Scientists have developed a new method to directly follow viral infections in living organisms. This method can make infected cells produce fluorescent proteins, which means that they light up and become easier to identify.
