CD3ε is a 20 kD chain of the CD3/T-cell receptor (TCR) complex, which is composed of two CD3ε, one CD3γ, one CD3δ, one CD3ζ (CD247), and a T-cell receptor (α/β or γ/δ) heterodimer. It is found on all mature T cells, NK T cells, and some thymocytes. CD3, also known as T3, is a member of the immunoglobulin superfamily that plays a role in antigen recognition, signal transduction, and T cell activation.Product Details
- Human, Cross-Reactivity: Chimpanzee
- Antibody Type
- Host Species
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA)
- The antibody was purified by affinity chromatography and conjugated with Spark NIR™ 685 under optimal conditions.
- Lot-specific (please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.)
- 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 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
* Spark NIR™ 685 has a maximum excitation of 665 nm and a maximum emission of 685 nm.
- Excitation Laser
Red Laser (633 nm)
- Application Notes
Additional reported application (for the relevant formats) include: immunohistochemical staining of frozen tissue sections4,5,8, immunofluorescent staining6, and Western blotting3.
