Detecting megakaryocytes by flow cytometry is never easy. These cells are usually very large and fragile. Therefore, we needed to give our assay every chance of labelling them. We chose this antibody because it has both CD41 and CD61 together. Also, it was on a fluorochrome that we were able to use in our multi-color panel. A full titration was performed before adding it to the panel. The result from the optimal volume is shown in the plot.

Experimental Design and Results Summary

Applications

Flow Cytometry

Sample

Human blood, bone marrow aspirate

Primary Incubation

15 minutes at Room Temp

Blocking Agent

None

Secondary Incubation

N/A

Tertiary Incubation

N/A

Detection

Red Laser (633 nm) and a filter around 774 nm

Results Summary

The results were good. We can see, even at 2.5uL per test (data shown in the image attached), that the antibody stained the cells of interest. There was a very good separation between the negatives and the positives (acceptable resolution). The background was very low.

Summary

The Good

good price, good resolution

The Bad

tough to compensate

The Bottom Line

If you need a good platelets/megakaryocyte marker, this will work nicely. But beware of compensation issues.
