Anti-CD3D antibody [EP4426] (ab109531)

Lanes 1 - 6: Merged signal (red and green). Green - ab109531 observed at 23 kDa. Red - loading control, ab8245, observed at 37 kDa.

This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab109531 and ab8245 (loading control) overnight at 4°C. Antibody binding was detected using Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at a 1:10000 dilution for 1hr at room temperature and then imaged.

IHC image of CD3D staining in a formalin fixed, paraffin embedded human B-Cell lymphoma tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab109531, 1/200 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

ab109531 staining CD3 in Jurkat cells by Flow Cytometry. Cells were fixed in paraformaldehyde and permeabilized in saponin. The sample was incubated with the primary antibody (1/100 in PBS) for 15 minutes at 4°C. A phycoerythrin-conjugated Goat anti-rabbit IgG (1/100) was used as the secondary antibody.
