To reduce the occurrence of sample-related bead aggregation, the following steps can be taken:
•Spin samples at 10,000 x g for 10 minutes immediately before preparing sample dilutions or loading samples into the plate.
•Resuspend the plate in Wash Buffer instead of Sheath or Drive Fluid. The plate must be read within a couple of hours, and the buffer should be switched to Sheath or Drive Fluid for longer storage.
•Dilute samples at a ratio of 1:2 or 1:4.
•Perform more wash cycles after the primary incubation step of the assay to remove substances that cause bead aggregation.

General description
- More flexible plate and plate washer options
- Improved performance with turbid serum/plasma samples
- Assay results equivalent to non- beads
- Automated washing avoids many problems associated with vacuum filtration washing
MILLIPLEX® Mouse Cytokine / Chemokine panel enables you to focus on the therapeutic potential of cytokines as well as the modulation of cytokine expression. Coupled with the Luminex® xMAP® platform in a bead format, you receive the advantage of ideal speed and sensitivity, allowing quantitative multiplex detection of dozens of analytes simultaneously, which can dramatically improve productivity.
Panel Type: Cytokines/Chemokines

It seems that the sample wells are experiencing low bead counts while the standard and control wells are unaffected. This issue is limited to 1 or 2 cytokines, while the rest show normal counts. It doesn't appear to be related to the instrument, bead loss, or inadequate bead mixing. What could be the possible reason for this discrepancy?

Does the addition of 25 µL of Assay Buffer to the sample well count as a dilution when using a Milliplex kit that does not require a sample dilution prior to loading the plate?
1 answer-
If the sample is not diluted prior to loading the plate, and the same volume of standard and sample are loaded, then there is no need to apply a sample dilution factor.
