Cell Fractionation of Pseudomonas aeruginosa
Authors:  Esteban Paredes-Osses and Kim R. Hardie, date: 10/05/2013, view: 7630, Q&A: 0
Pseudomonas aeruginosa is a Gram negative bacterium. Separating the cell envelope compartments enables proteins to be localized to confirm where in the cell they function. Cell fractionation can also provide a first step in a protein ...
