💡 Big idea: GFP is a visual reporter that makes an invisible protein visible; chromatography exploits binding affinity to isolate it.
- 0-10Read chromatography notes; define chromatography and elution
- 10-25Explain GFP reporter mechanism; annotate UV signal
- 25-45Diagram protein binding to column resin and wash steps
- 45-58Add elution step to diagram; label target fraction
- 58-70Predict which numbered fraction glows; write prediction
- 70-80Submit labeled diagram to tracker; confirm lab readiness
- • Tomorrow you run the column, so today you need to understand what it is actually doing.
- • GFP is the tracking beacon: wherever it glows, your protein is.
- • Chromatography is the separation engine: it holds your protein while everything else washes away.
- • Understanding affinity and elution is a Lab SOPs and Molecular Technology skill on the WebXam.
- 1Read the chromatography notes in the PLTW course shell and define chromatography and elution.
- 2Explain why GFP glowing under UV light marks where the target protein is.
- 3Diagram a protein binding to a column and then eluting in a chosen fraction.
- 4Predict which fraction should glow if purification worked.
- 5Submit a labeled chromatography diagram as PLTW tracker evidence.
- • You'll be able to explain how GFP marks the target protein.
- • You'll be able to describe how chromatography separates and elutes proteins.
- • GFP fused to the target protein fluoresces green under UV light, revealing which fraction contains the protein.
- • Affinity chromatography uses a resin that binds the target specifically, letting other proteins wash through.
- • Elution uses a competing molecule or change in buffer conditions to release the bound target protein.

Day 2 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open Activity 4.1.3 GFP Protein Purification in myPLTW and diagram how GFP and affinity chromatography track and separate the target protein.
Mark the GFP-and-chromatography entry complete and attach your labeled chromatography diagram.
Purification overview exit ticket should be done (Monday); chromatography diagram due today.

All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.
Today's PLTW tracker
Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.
