CD86 PE

Catalog Number:

553692

Our lab is concerned with studying transcriptome and signaling changes that occur during transitional B-cell development. This is a major checkpoint in peripheral tolerance where autoreactive B-cell clones are purged. Typically, splenocytes from C57BL/6 and various mutant strains are used.

Experimental Design and Results Summary

Applications

Flow Cytometry

Sample

C57BL/6 splenocytes

Primary Incubation

15-20min in FACS buffer

Blocking Agent

Fc block 5min prior

Secondary Incubation

NA

Tertiary Incubation

NA

Detection

Flow cytometry

Results Summary

C57BL/6 mice were ip injected with Listeria Monocytogenes. Splenocytes were collected 18-48 hours later and subsequently stained for flow cytometry. CD86 expression on B-cells typically becomes elevated upon activation. Results show CD86 surface expression is increased on B-cells (both immature and mature).

Additional Notes

1:200 final dilution for 1 million cells

Summary

The Good

CD86 PE is able to detect activation of B-cells

The Bad

NA

The Bottom Line

This antibody gives reliable detection of CD86 which ranged in expression over a fairly wide spectrum
