Product Name:

PE anti-mouse CD138 (Syndecan-1)

Catalog Number:

142504

Our goal was to specifically label a subset of NKT cells in mice by flow cytometry and microscopy. We selected this marker based on a previous publication noting success. We tested different fluorophores, and found PE to be the best color due to the relatively low abundance of surface CD138.
