Lab — Cell Free Induction

Info

MIT/Harvard: No in‑person lab protocol this week (per schedule).
Global Nodes: Use the PDF protocol below.

Objective

Induce a reporter in a cell‑free transcription‑translation (TX‑TL) system and quantify expression changes between treatments.

Concepts You’ll Learn

  • TX‑TL reaction components and setup
  • Induction strategies and controls
  • Fluorescence quantification & fold‑change analysis

Protocol

Post‑Lab Questions (Mandatory)

  1. Using your lab images (or provided images), compute fluorescence fold‑change between treatments. Discuss LacI function in the context of the circuit used.
  2. What would you expect if the same induction were performed in E. coli BL21(DE3)?
