Is there a short tandem repeat (STR) database for mouse cell line authentification?

Hi, Have a mystery cell line of mouse origin that I need help identifying. I used the IDEXX service for STR analysis but the results were inconclusive. Seems like the database is forthcoming but...

How would you distinguish granulocytic myeloid derived suppressor cells from a neutrophil?

The challenging part of this is that once a tumor has collapsed, presumably infiltrating neutrophils will "mop up" and look like granulocytic MDSC's i.e. ly6c mid, ly6g hi, cd11b+.

Has anyone managed to successfully lower the number of beads for luminex detection of cytokines?

After seeing how little of the sample is consumed to acquire the desired number of beads, I thought we may be able to stretch the kit by lowering the number of beads per sample. Hopefully this...
