E. coli Expression Systems: Host Selection, Vectors, and Industrial Titers

Escherichia coli Expression Systems

Advantages of Microbial Expression Systems

Bacterial and yeast systems share several advantages over mammalian expression systems:

  • Higher growth rate and cell densities.
  • Robustness at the cellular level.
  • High expression levels.
  • Simple cultivation and are easy to scale-up.

The selection of the appropriate expression system is determined by the characteristics of the target protein or product.

Physics Fundamentals: Key Concepts, Formulas, and Energy Scales

Energy & Power

• Energy: ability to do work; conserved; transforms among heat, chemical, mechanical, electrical, nuclear, etc.

• Power: rate of energy use; determines how fast work is done or energy is converted.

Units & Conversions

• calorie (cal): energy to raise 1 g water by 1 °C ~ Calorie (food Cal) = 1 kcal = 1 000 cal ~ joule (J): SI unit; 1 J = 1 kg·m²/s²

• kilowatt-hour (kWh): industrial/domestic unit; 1 kWh = 3.6 MJ ≈ 1 000 Cal

• household uses ~12 000 kWh/yr

Descriptive Measures: Center and Variability

Measures of Variation

  • Standard Deviation (SD): The average measure of distance between data points and the mean (the square root of the variance). It indicates how far the data is, on average, from the mean.
    • Calculation: Find the variance and take its square root.
  • Coefficient of Variation (CV): Used to compare the standard deviation of two different data sets. Shown as a percentage, it measures variation relative to the mean.
    • Formula: CV = (Standard Deviation

Early Models of Industrial Organization

  • Cournot (1838): Used mathematics to study economics, price formation with a single supplier (monopoly), and oligopoly with simultaneous quantity setting.
  • Bertrand (1883): Analyzed oligopoly with simultaneous price setting.
  • Stackelberg (1934): Studied sequential setting of quantities in an oligopoly.
  • Hotelling (1929) and Chamberlin (1933): Introduced the concept of product differentiation.
