Cell Analysis
Cell Analysis refers to a broad range of assays for studying the function and localization of proteins in living and fixed cells. Cell Analysis covers assays that are not more precisely described as one of the other Multiwell Plate Assay types.
RGB channel images are not quantified.
Overview
-
A Plate Template is required for Cell Analysis. Plate Templates are created in the Empiria Studio Experiment Designer. In a Plate Template, you designate which wells will contain which samples and controls. During analysis, choose the multiwell plate image to analyze and the Plate Template to use for analysis. Wells on the image that correspond to wells designated on the Plate Template will be quantified. Statistical values will be calculated from the quantification values.
See Getting Started with Plate Templates for more information about creating Plate Templates. See Empiria Studio® Software Multiwell Plate Calculations Reference for more information about calculations.
-
Plate Templates are divided into categories. The Plate Template categories match the Cell Analysis categories. When you start an analysis workflow, choose the category that matches the Plate Template you will be using.
-
The instructions on this page are applicable to all categories of Cell Analysis.

Quantify wells
On this page, ensure quantification is set up correctly for your plate image.
Image display options are available above the image. Only the image display is changed; the original image file remains the same.
-
Zoom: Click the zoom buttons above the image to make the displayed image smaller or larger . A zoom level, shown as a percentage relative to the size of the software window, is shown next to the zoom buttons.
-
Display Settings: Click
to change display settings.
-
Display Channels: Click
to select the channels you want to display.
-
Display Well IDs: Click to stop showing Well IDs.
-
The plate grid is the grid of well circles inside a rectangular outline overlaying the image. The plate grid is used to specify well size and location.
-
Only well circles that correspond to the wells designated in the Plate Template are quantified.
-
These well circles are identified by default with a Well ID label.
-
Ensure the well circles being quantified are placed on top of the wells on the image that need to be quantified.
-
Adjust well size: Click Decrease or Increase to change the size of all the well circles on the image. Wells in 6-well and 12-well Plate Templates can be adjusted individually. Depending on your analysis, you may need to keep all wells the same size. If you have adjusted wells individually to different sizes and would like all the wells to be the same size again, you can click Decrease or Increase to bring the wells back to the same size.
-
Adjust plate grid rotation: Click
to rotate the entire plate grid counter-clockwise or
to rotate the entire plate grid clockwise.
-
Adjust plate grid location: Click the rectangular outline of the plate grid. Drag the plate grid so that the well circles in the plate grid cover the appropriate wells on the plate image.
Choose the channel to use for normalization from the Normalization Channel list. For example, this will be the channel with a cell stain such as CellTag™ 520 Stain or CellTag 700 Stain. The Signal values from this channel will be used to calculate normalized values in other channels. See Empiria Studio® Software Multiwell Plate Calculations Reference for more information about normalization calculations.
You may not want to quantify all the wells that were designated for quantification in the Plate Template.
-
If there is a well you do not want to quantify, select the well and then click Exclude Well.
-
To quantify a well that had previously been excluded, select the well and then click Include Well.
If you select Use trim value calculations, the pixels with the highest and lowest 5% of pixel intensity values in each well will be excluded from the calculation of Total and Signal. Formulas that normally use Total and Signal will instead use Trim Total and Trim Signal.
It is up to the researcher to decide if Trim values should be used. See Empiria Studio® Software Multiwell Plate Calculations Reference for more information.
Click Analysis Table to view well quantification data, including Total, Signal, Background, and Normalized Signal.
Click to export all the data to a spreadsheet.
See Empiria Studio® Software Multiwell Plate Calculations Reference for more information about the quantification data in the table.
Set up chart
On this page, create a chart or charts with normalized signal, fold change, and/or percent change. You can create multiple charts.
-
Click Start New.
-
In the Start New Chart dialog:
-
Select Normalized.
-
Enter a Chart Name that will help you identify this chart in a list of charts.
-

-
If a chart is already displayed, you can select Use current chart settings to use the X-Axis, Series, and text from the current chart on the new chart.
-
-
Click Start.
-
Fill in the appropriate X-Axis and Series information in the data table.

Some data cannot be included in a chart
You may see the following message at the top of the Set Up Charts page.
Some data cannot be included in a chart. Click this link for more details.
This message indicates that data from at least one Well Group cannot be included in a chart. The check box in the Include column will be unavailable for Well Groups that cannot be included in a chart.
Possible solutions
-
Ensure that at least two background wells are designated in the Plate Template for the problematic Well Group.
-
Ensure that the background wells are being quantified on the Quantify wells page. Wells that have been excluded from quantification are marked with this symbol: .
-
If something is wrong with the wells and you do not want to include them in your analysis, it may be best to run the experiment again.
Charts cannot be created
You may see a banner with the following heading on the Set Up Charts page.
Chart cannot be created.
If you see this message, start with the following steps to identify and resolve the problem.
Possible solutions
-
On the Quantify wells page, ensure that a normalization channel is chosen in the Normalization Channel list.
-
In the Plate Template, ensure that background wells and at least one other type of well (positive, negative, sample) have been designated.
-
On the Quantify wells page, ensure that the background wells and the wells of the other well type are being quantified. Wells are not quantified if they have been "excluded". Wells that have been excluded are marked with this symbol: . If a well that you want to include has been excluded, select the well and click Include.
-
If something is wrong with the wells and you do not want to include them in your analysis, it may be best to run the experiment again.
