Protocol and data stations
Wed, Dec 2, 2026 · Week 15 · Genetics of Disease (Medical Interventions)
Today's goal: Rotate through hands-on stations modeling protein purification, HLA matching, and tissue-engineering data.
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Three-station data table (my recorded results):
- Purification station (chromatography column): Collected 6 fractions. Protein assay was strongest in Fraction 4 (dark blue, high signal) and Fraction 5 (medium), with Fractions 1-3 and 6 near zero. Conclusion: the target protein eluted in Fractions 4 and 5.
- HLA-matching station: Compared donor and recipient cards across 6 HLA loci. Matches at 5 of 6 loci; one mismatch at HLA-DR. Crossmatch score recorded as 5/6, flagged as a strong but not perfect match.
- Tissue station (scaffold comparison): Scaffold A (dense mesh) showed cell coverage about 45 percent after the modeled growth period; Scaffold B (porous mesh) showed about 78 percent. Note: the porous Scaffold B supported more cell growth, likely because pores let nutrients and cells move deeper.
One-line reading of each: high-protein fractions = 4 and 5; crossmatch = 5/6 (usable); better scaffold = B.
(Tip: write the actual number in every cell, even an estimate like 78 percent, because a data table with words but no values loses the most points.)
This model shows the level of evidence and organization needed to complete: Completes the three-station data table: recorded results from the protein-purification station, the HLA-matching station, and the tissue-scaffold station.
- Name the variables and include units.
- Enter observations without changing the raw values.
- Check labels, calculations, and patterns before interpreting the data.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
Also due today: turns in the completed data table on Schoology under the Unit 4 Protocol and Data Stations assignment.

Claim ceiling: Today's evidence supports a classroom claim about today's lesson. It cannot prove causation, diagnose a real patient, or justify action outside this room.
One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

It builds this reusable test skill: Interpreting a chromatography fraction result.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
