Replicate Analysis

Replicate measurements are critical for Quantitative Western blot analysis. The purpose of Quantitative Western blot is to monitor changes in the relative abundance or modification of a target protein within a group of samples. For example, does the experimental treatment cause an increase or decrease in target abundance compared to a control condition?

Replicate samples confirm the validity of observed changes in protein levels. Without replication, it is impossible to know if an effect is real or simply an artifact of experimental noise. Biological and technical replicates are both important, but each type of replicate addresses different questions.

In the Replicate Analysis workflow, you will analyze replicate Treatment Groups from different Experiments to determine fold change, average fold change, standard deviation, and percent coefficient of variation for the replicate Treatment Groups.

Name

To help with record-keeping, give every Experiment a distinct name. The description field provides space for you to include important details about the Experiment.

Choose Experiments

Choose the replicate Target Analyses you need to analyze and add the Analyses to the Replicate Analysis.

Choose treatment groups

Combine replicate Treatment Groups from different Experiments into Replicate Groups for analysis. The fold change, average fold change, standard deviation, and percent coefficient of variation will be calculated for Replicate Groups.
