The antibody was purified by affinity chromatography, and conjugated with PerCP/Cy5.5 under optimal conditions. The solution is free of unconjugated PerCP/Cy5.5 and unconjugated antibody.
Concentration:
0.2 mg/ml
Storage & Handling:
The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is ≤ 0.5 µg per 106 cells in 100 µl. It is recommended that the reagent be titrated for optimal performance for each application.
* PerCP/Cy5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.
Application Notes:
Additional reported applications (for the relevant formats) include: immunoprecipitation1, complement-mediated cytotoxicity1,3, immunohistochemical staining1,4 of acetone-fixed frozen sections, in vitro stimulation of T cells1 and depletion2 of CD3+ cells in vivo. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm sterile-filtered) is recommended for functional assays (Cat. No. 100208).

C57BL/6 splenocytes stained with 17A2 PerCP/Cy5.5
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. The 17A2 antibody recognizes ε/γ (but not ε/δ) of CD3 complex. The 17A2 antibody can induce T cell activation and has been reported to deplete CD3+ cells in vivo.
