1101005 50 µg $20.00       
1101010 500 µg $80.00       
Clone: 17A2
Isotype: Rat IgG2b, κ
Reactivity: Mouse
Immunogen: γδTCR-positive T-T hybridoma D1
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
Application:

FC - Quality tested
IHC-F - Validated
IP - Reported in the literature

Application Notes:

The 17A2 antibody recognizes ε/γ (but not ε/δ) of the CD3 complex. The 17A2 antibody can induce T cell activation and has been reported to deplete CD3+ cells in vivo. Additional reported applications (for the relevant formats) include: immunoprecipitation1, complement-mediated cytotoxicity1,3, immunohistochemical staining of acetone-fixed frozen sections1,4, in vitro stimulation of T cells1 and depletion of CD3+ cells in vivo2.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 mouse splenocytes stained with

C57BL/6 mouse splenocytes stained with purified 17A2, followed by anti-rat IgG FITC

C57BL/6 mouse frozen spleen section

C57BL/6 mouse frozen spleen section was fixed with 4% paraformaldehyde (PFA) for ten minutes at room temperature and blocked with 5% FBS for 30 minutes at room temperature. Then, the section was stained with 10 µg/mL of Purified CD3 (clone 17A2) and Alexa Fluor® 488 anti-mouse/human CD45R/B220 antibody (green) overnight at 4°C, followed by 2.5 µg/mL of Alexa Fluor® 594 anti-rat IgG2b (clone MRG2b-85) (red) for two hours at room temperature. The image was captured by 10X objective.



Description:

CD3, also known as T3, is a member of the Ig superfamily and primarily expressed on T cells, NK-T cells, and at different levels on thymocytes during T cell differentiation. CD3 is composed of CD3ε, δ, γ and ζ chains. It forms a TCR complex by associating with TCR α/β or γ/δ chains. CD3 plays a critical role in TCR signal transduction, T cell activation, and antigen recognition by binding the peptide/MHC antigen complex.

Other Names: T cell antigen receptor complex, T3
Structure: Ig superfamily, CD3/TCR, 20 kD
Distribution: Thymocytes (differentiation dependent), mature T cells, NK-T cells
Function: Antigen recognition, TCR signal transduction, T cell activation
Ligand Receptor: Peptide antigen/MHC-complex
