“Zinc finger was challenging due to sophisticated protein engineering...”

Story of claim

Zinc finger nucleases require complex protein engineering for specificity in gene editing, making them cumbersome and often unsuccessful, as discussed by Feng Zhang.

  • Goal: To improve specificity and efficiency in gene editing techniques.
  • Proof: Protein engineering required for zinc fingers was sophisticated and often unsuccessful, limiting their application in precise gene editing.
  • Nuances:
    • Zinc fingers needed arrays for specificity.
    • Engineering was cumbersome and often unsuccessful.
  • Impact on Life: The challenges hindered progress in gene editing, prompting researchers to seek more efficient alternatives like CRISPR.

Investments

  • Price: High cost due to complex engineering requirements
  • Time: Several weeks to months for successful engineering
  • Effort: High effort due to complex engineering.

Risks

Complex engineering may lead to errors, decreasing efficiency.

Alternatives

  • CRISPR-Cas9 as a more efficient and easier-to-use option
