KAKAKPVTRGAGA, corresponding to amino acids 156-168 of Human CD3 Epsilon chain.
Our Abpromise guarantee covers the use of ab5690 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|IHC-Fr||1/100. PubMed: 18628996|
|WB||Use a concentration of 0.5 - 2 µg/ml. Predicted molecular weight: 23 kDa.|
|IHC-P||1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. The recommended starting incubation time is 10min.|
|IHC-FoFr||Use at an assay dependent concentration. PubMed: 20126467|
|ICC/IF||Use at an assay dependent concentration. PubMed: 23874197|
Lanes 1 - 6: Merged signal (red and green). Green – ab5690 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 ab5690 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.
No positive immunostaining for CD3ε, a pan T cell marker (ab5690), was detected in the corneas of scrambled siRNA-treated mice (A) at 5 days p.i. In contrast, positive immunostaining (red) was observed in the peripheral cornea of HIF-1α silenced animals (B). The control sections shown in (C) and (D) were immunostained with species-specific IgG and were positive for SYTOX Green nuclear stain only. Images shown are representative of three independent experiments each with three mice per group. Magnification = 180×; inset = 335×.
ab5690 at 1/100 staining mouse lymph node tissue sections by IHC-Fr. The tissue was acetone fixed and blocked with serum before incubation with the antibody for 1 hour. An Alexa Fluor ® 488 conjugated goat anti-rabbit antibody was used as the secondary.
IHC image of CD3 staining in a formalin fixed, paraffin embedded normal human tonsil 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 ab5690 at 1/100 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.

ab5690 staining rat spleen tissue sections by IHC-P. Sections were formaldehyde fixed and subjected to heat mediated antigen retrieval in sodium citrate buffer (10mM Sodium Citrate, 0.05% Tween 20, pH 6.0) prior to blocking in 5% normal goat serum + 1% BSA for 2 hours at 37°C. The primary antibody was diluted 1/200 and incubated with the sample for 16 hours at 4°C. A biotinylated goat anti-rabbit antibody, diluted 1/100, was used as the secondary.
