Product name: CD44 Monoclonal Antibody (1M7.8.1)
Antibody type: Monoclonal
Antigen: Other
Description: MA4405 targets CD44 in FACS, IA, IF, IP, and WB applications and shows reactivity with mouse and Human samples. The MA4405 immunogen is mouse 80-95 kD lymphocyte surface glycoprotein H-CAM (CD44). MA4405 detects a standard 85-kDa isoform of CD44 and a number of high molecular mass variant isoforms. This antibody is produced by injecting Rat IgG secreting hybridoma cells into the peritoneum of mice. The resulting ascites is collected from the mice and the antibody is purified. This product is a Low Endotoxin formulation. This product has been tested for endotoxins by limulus amoebocyte lysate (LAL) assay and contains an endotoxin concentration of less than or equal to 10 endotoxin units per milligram (EU/mg).
Reactivity: Human, Mouse
Host: Rat
Isotype: IgG

Experimental details: Immunofluorescent analysis of CD44 (green) showing staining in the membrane of BAF-3 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a CD44 monoclonal antibody (Product # MA4405) in 3% BSA-PBS at a dilution of 1:20 and incubated overnight at 4ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.
