Protein Data

Bacterial Cells: E. coli or Salmonella typhimurium

Cell Data per cell per liter at 109 cells per ml
Wet Weight 9.5 X 10-13 g 0.95 g
Dry Weight 2.8 X 10-13 g 0.28 g
Total Protein 1.55 X 10-13 g 0.15 g
Volume 1.15 µm3 = 1 femtoliter  
Protein Conc. in the cell: 135 mg/ml
Theoretical maximum yield for a 1 liter culture (109 cells /ml) if protein of interest is:
0.1% of total protein:   150 µg/liter
2.0% of total protein:  3 mg/liter
50.0% of total protein:  75 mg/liter
