💡 Big idea: How does following a precise multi-step procedure with proper controls produce a result you can trust?

  1. 0-8 minDon goggles and gloves; confirm plate layout matches Tuesday's plan before opening any reagent
  2. 8-25 minAdd reagents to each well in the correct order per the numbered procedure; keep controls in their designated wells
  3. 25-45 minWait incubation period exactly as written; do not disturb the plate; record start time
  4. 45-58 minAdd detection reagent; observe and record color in every well as it develops
  5. 58-68 minPhotograph the plate next to the layout sheet; save image to portfolio folder
  6. 68-80 minNote whether controls matched predictions; write one sentence validating (or flagging) the run
Mr. Mendoza's 5-minute intro
  • 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.
Do this, step by step
  1. 1Put on goggles and gloves and confirm your plate layout matches your plan.
  2. 2Add reagents to each well in the correct order, keeping controls separate.
  3. 3Wait the required incubation times exactly as written in the procedure.
  4. 4Add the detection reagent and record the color that develops in every well.
  5. 5Photograph the plate next to your layout sheet for your portfolio.
  6. 6Note whether your positive and negative controls matched your predictions.
You'll be able to
  • 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.
Know by the end
  • 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.

Safety / SOP
  • 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.
