Immunofluorescence analysis of Syndecan-1 / CD138 was performed using 70% confluent log phase COLO 205 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Syndecan-1 / CD138 Rabbit Polyclonal Antibody (Product # PA5-16918) at 2µg/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjµgate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing cytoplasmic and nuclear localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA5-16918 targets CD138 in IHC applications and shows reactivity with Human samples.
The PA5-16918 immunogen is recombinant protein encoding aa 18-218 human CD138.
CD138/Syndecan-1 is a transmembrane heparin sulphate proteoglycan which is made up of one core protein and five glycosaminoglycan. CD138 is expected to play a role in cell adhesion. It is expressed on the surface of pre-B cells and plasma cells but is absent from mature B cells. It is a selective marker for B cell lymphoblastic leukemia and lymphoplasmocytoid leukemia. It is lost from the apoptotic myeloma cells; hence is a useful marker for viable myeloma cells.
