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.Product Details
- Antibody Type
- Host Species
- γδTCR-positive T-T hybridoma D1
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
- The antibody was purified by affinity chromatography, and conjugated with APC/Cyanine7 under optimal conditions. The solution is free of unconjugated APC/Cyanine7 and unconjugated antibody.
- 0.2 mg/ml
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
FC - Quality tested
- 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.
- Excitation Laser
Red Laser (633 nm)
- 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.
- Additional Product Notes
- BioLegend is in the process of converting the name APC/Cy7 to APC/Cyanine7. The dye molecule remains the same, so you should expect the same quality and performance from our APC/Cyanine7 products. Please contact Technical Service if you have any questions.
