Default Luminex® assay designs include properties specific to the technology, and beyond the default properties included in General assay designs. The general process for designing an assay is described in Design a New Assay. A design based on the built-in defaults for Luminex is defined in the Luminex assay tutorials (Step 1: Create a New Luminex Assay Design). This page offers additional details on the default properties defined for this type of assay.
Using this option is particularly helpful when you have large runs that are slow to upload. If this setting is enabled, assay uploads are processed as jobs in the data pipeline.
You will see the Upload Jobs page while these runs are being processed. Your current jobs are marked "Running." When the jobs have completed, you will see "Completed" instead of "Running" for the job status for each. If you see "Error" instead of completed, you can see the log files reporting the problem by clicking on "Error." Luminex assay properties (batch, run, well role/titration settings, and analyte properties) are also written to the log file to assist in diagnosing upload problems.
When the Status of all of your jobs is "Completed", click the Description link for one of the runs to see all of the data for this run.
Add any transform script here by clicking Add Script, then either uploading the script or specifying the path. During script development, you can also check the box to Save Script Data for Debugging.

If you want the assay to Auto-Link Data to Study, select the target study here. You can also choose the Linked Dataset Category if desired.

The user is prompted for batch properties once for each set of runs during import. The batch is a convenience to let users set properties once and import many runs using the same suite of properties.
Included by default:
The user is prompted to enter run level properties for each imported file. These properties are used for all data records imported as part of a Run.
Included by default:
The user is prompted to select well roles next. If a sample appears at several different dilutions, we infer you have titrated it. During the import process for the run, you can indicate whether you are using the titrated sample as a standard, quality control, or unknown.
Included by default:
In this panel you will also see checkboxes for Tracked Single Point Controls. Check a box if you would like to generate a Levey-Jennings report to track the performance of a single-point control. Learn more in the Level II tutorial which includes: Step 5: Track Analyte Quality Over Time and Track Single-Point Controls in Levey-Jennings Plots.
On the same page as well roles, the Analyte Properties section is used to supply properties that may be specific to each analyte in the run, or shared by all analytes in the run. They are not included in the data file, so need to be entered separately. For example, these properties may help you track the source of the analytes or beads used in the experiments, for the purpose of quality control. In the second Luminex tutorial we track two lots of analytes using these properties.
For each analyte the user enters (a checkbox allows entering the same value for all analytes for any property):
When the user imports a Luminex data file, the server will try to find these properties in the header and footer of the spreadsheet, and does not prompt the user to enter them.
Included by default:
The Excel file format includes a single field for sample information, the Description field. LabKey Server will automatically attempt to parse the field to split it into separate fields if it contains information like Participant and Date. Formats supported include:
The user is prompted to enter data values for each row of data associated with a run.
Not included by default in the design, but should be considered:
The LabKey Luminex transform script calculates additional values (e.g., curve fits and negative bead subtraction) that are used by the LabKey Luminex tool. Custom batch, run, analyte, and data properties used by this script are covered in these pages: Customize Luminex Assay for Script and Review Fields for Script. Some useful assay properties are listed here:
Assay Properties
| Field Label | Value | Description |
|---|---|---|
| Editable Runs | Unchecked | When selected, allows run data to be edited after import by default. If you allow editing of run data, you may wish to uncheck Advanced Settings > Display Options > Show on update form... in the domain editor for each field used or calculated by the script. The script runs only on data import, so preventing later editing of such fields is necessary for calculated data to continue matching the values displayed for the fields in the assay. |
| Import in Background | Unchecked | When selected, runs are imported in the background, allowing you to continue work on the server during import. This can be helpful for importing large amounts of data. This tutorial leaves this value unchecked merely for simplicity of workflow. For further information on what happens when you check this property, see Luminex Properties. |
| Transform Script | -- | Path to the LabKey Luminex transform script. The path provided must be local to your server. The default path provided in a XAR will be usable only on the server where the XAR was created. |
