💡 Big idea: How does following a precise multi-step procedure with proper controls produce a result you can trust?
- 0-8 minDon goggles and gloves; confirm plate layout matches Tuesday's plan before opening any reagent
- 8-25 minAdd reagents to each well in the correct order per the numbered procedure; keep controls in their designated wells
- 25-45 minWait incubation period exactly as written; do not disturb the plate; record start time
- 45-58 minAdd detection reagent; observe and record color in every well as it develops
- 58-68 minPhotograph the plate next to the layout sheet; save image to portfolio folder
- 68-80 minNote whether controls matched predictions; write one sentence validating (or flagging) the run
- • This is the most technically demanding day of the unit; every step you practiced Tuesday exists to make this run succeed.
- • Real clinical ELISA runs in a hospital lab follow the same sequence you are about to use.
- • Work slowly and methodically; speed kills accuracy in wet lab work.
- • Exit goal: a complete data table and a photographed plate with both controls validated.
- 1Put on goggles and gloves and confirm your plate layout matches your plan.
- 2Add reagents to each well in the correct order, keeping controls separate.
- 3Wait the required incubation times exactly as written in the procedure.
- 4Add the detection reagent and record the color that develops in every well.
- 5Photograph the plate next to your layout sheet for your portfolio.
- 6Note whether your positive and negative controls matched your predictions.
- • You will be able to run an ELISA following a procedure safely.
- • You will be able to record well colors accurately.
- • You will be able to check controls to validate a run.
- • ELISA steps must be performed in exact order; adding reagents out of sequence destroys the binding chain and invalidates results.
- • Incubation times are critical: too short and binding is incomplete; too long and background signal builds up.
- • Checking controls immediately after the run tells you whether to trust any of the other results.

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open Activity 1.1.5 ELISA (protocol and results) in myPLTW and follow the wet-lab protocol to run your ELISA today.
Record color results for every well and note whether your positive and negative controls matched predictions.
Plate-layout plan should be done (Tuesday); well-color data recorded and photographed today.
Plate photo and color-result data table in notebook and portfolio folder.
All PLTW activities are completed inside the PLTW course environment — this page only gives direction. Submit producibles on Schoology.

Lab & supplies
- • Goggles and gloves are mandatory before any reagent is opened and must stay on until cleanup is complete.
- • Treat all samples as potentially biohazardous: use disposable tips and do not pipette by mouth.
- • Dispose of used tips, plate, and reagents in the designated biohazard waste container.
- • Add stop solution in a fume hood or well-ventilated area if required by the reagent SDS.
- • Spills on skin: rinse immediately with water for 15 minutes; report to teacher; reference the reagent SDS for Section 4.
- • Do not eat, drink, or touch your face in the lab area.
