We used this antibody to evaluate whether cells expressed an increased level of MHC II molecules containing the CLIP peptide on their surface.

Experimental Design and Results Summary

Applications

Flow Cytometry

Sample

Primary murine CD45+ and CD45- cells

Primary Incubation

1:5 dilution for 30 minutes at 4 degrees C

Blocking Agent

2.4G2 Fc block

Secondary Incubation

NA

Tertiary Incubation

NA

Detection

Canto II

Results Summary

The antibody stained well on CD45+ DC and B cells. We used the isotype control from Santa Cruz or MHC II knockout mice as negative controls as there was a high background with an FMO. Additionally, there was a high background staining of both the antibody and the isotype control on non-hematopoietically derived cells including endothelial cells, necessitating the use of MHC II KO mice as a negative control.

Summary

The Good

Good staining on hematopoeitic cells

The Bad

Can have a high level of background

The Bottom Line

You need a good negative control such as MHC II KO mice or a non I-Ab expressing mouse strain.
