ELISA Standard Curve

The process of using an ELISA Standard Curve involves several steps:

Step 1: Prepare Layout

  1. Plate Selection: Confirm the plate size (currently supporting 96-well plates).

  2. Layout Setup: You have various ways to set up the layout:

    • Manually input values.

    • Copy and paste data from Excel/Word.

    • Import data via drag and drop using table format files.

    • Update dilution factors (default to 1) for sample documentation.

  3. Layout Rules:

    • Use the first cell for concentration units (e.g., ug/ml).

    • Mark standard concentrations with "CONC" in the first column or row.

    • Designate standard wells as "STD" and blank wells as "BLANK."

    • Duplicate well names are treated as duplicates.

    • Leave wells blank to exclude data points.

  4. Best Practices:

    • Run replicates for standards and samples.

    • Conduct a standard curve and include positive and blank controls.

    • Dilute samples within the linear range of the standard curve.

Step 2: Prepare Data

  1. Data Entry: Copy absorbance data into the 96-well plate.

  2. Data Exclusion: Leave wells blank to exclude data points.

Step 3: Perform Analysis

  1. Average Blank Absorbance: Calculate and display the average value of blank wells.

  2. Background Absorbance Subtraction: Normalize data by subtracting the average blank absorbance.

  3. Average Standard Absorbance: Calculate absorbance values for each standard concentration.

  4. Fit Standard Absorbance: Utilize regression methods (defaulting to linear) to fit standard absorbance to concentrations.

  5. Plot Standard Curve: Graph mean absorbance against protein concentration with a best fit curve.

  6. Calculate Metrics:

    • Concentration: Derive final concentrations considering dilution factors.

    • Standard Deviation (SD) and Coefficient of Variation (CV): Assess variability and accuracy of results.

  7. Advanced Adjustments:

    • Optical Density (OD), Dilution Factor, Data Transform, and Fit Method can be edited for customization.

Labii's ELISA Data Analysis widget streamlines ELISA layout design, data documentation, and analysis within an ELN, eliminating the need for multiple software tools. The process ensures replicability, accuracy, and efficiency in ELISA analysis.
