What a finished product looks like

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.

Dilution and ELISA model report

Completes: A packaged submission with the labeled standard curve, the model ELISA data table, a short interpretation of which samples were positive, and one source of error.

Interpretation: Well 1 was positive because its color matched the most concentrated standard on my curve, while Well 4 was effectively negative. I knew this by reading each well's color signal across to the best-fit line and down to its concentration.

Source of error: reading colors by eye is subjective, so two people might assign slightly different concentrations to a medium-blue well; a plate reader would reduce this error.

For the wet lab I want to: pipette more carefully so my dilution steps are exactly tenfold.

Also due today: Submit graph, data table, and interpretation in the course shell.

WebXam problem for today's skill

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.

WebXam-style domain: Bio-Molecular TechnologySelf-check skill: Identifying a source of measurement error in a colorimetric assay

A team reads their model ELISA colors by eye and assigns concentrations from a standard curve. Which is a real source of measurement error in this method?
