Immunohistochemical staining of lymphocytes and endothelial cells. The frozen section of normal mouse small intestine was reacted with 3E2 mAb. The positive staining can be identified by the intense brown labeling of endothelium, lymphocytes, and stroma of the lamina propria.

Preparation And Storage
Recommended Assay Procedures
Immunohistochemistry: The 3E2 antibody is recommended to test for immunohistochemical staining of acetone-fixed frozen sections and zinc-fixed paraffin sections. Tissues tested were mouse spleen and thymus. The clone 3E2 is not recommended for formalin-fixed paraffin embedded sections. The antibody stains lymphocytes, dendritic cells, and macrophages. The isotype control recommended for use with this antibody is purified hamster IgG (Cat. No. 550344). For optimal indirect immunohistochemical staining, the 3E2 antibody should be titrated (1:10 to 1:50 dilution) and visualized via a three-step staining procedure in combination with biotinylated anti-hamster cocktail (Cat. No. 550335) as the secondary antibody and Streptravidin-HRP (Cat. No. 550946) together with the DAB detection system (Cat. No. 550880). More conveniently, the Anti-Hamster Ig HRP detection kit (Cat. No. 551012) that contains the biotinylated secondary antibody, antibody diluent, streptavidin-HRP and DAB substrate can be used for staining.

Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at http://www.bdbiosciences.com/documents/hamster_chart_11x17.pdf.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- This antibody has been developed for the immunohistochemistry application. However, a routine immunohistochemistry test is not performed on every lot. Researchers are encouraged to titrate the reagent for optimal performance.
- An isotype control should be used at the same concentration as the antibody of interest.

Companion Products
The 3E2 monoclonal antibody specifically binds to CD54 (ICAM-1), a 95-kDa member of the Ig superfamily found on lymphocytes, vascular endothelium, high endothelial venules, epithelial cells, macrophages, and dendritic cells. ICAM-1 is a ligand for LFA1 (CD11a/CD18) and Mac-1 (CD11b/CD18). Its expression is upregulated upon stimulation by inflammatory mediators such as cytokines and LPS. Studies with mouse Icam1-transfected antigen-presenting cells, with CD54-blocking antibodies, and in CD54-deficient mice indicate that CD54 participates in inflammatory reactions and antigen-specific immune responses. In addition, there is evidence that CD54 is a receptor involved in MHC-non-restricted responses to weakly immunogenic tumor cells. The 3E2 antibody has been reported to block in vitro and in vivo intracellular adhesion events involved in immune responses.
