Product Details
- Verified Reactivity
- Human
- Antibody Type
- Monoclonal
- Host Species
- Mouse
- Formulation
- 0.2 ?m filtered in phosphate-buffered solution, pH 7.2, containing no preservative. Endotoxin level is <0.01 EU/?g of the protein (<0.001 ng/?g of the protein) as determined by the LAL test.
- Preparation
- The Ultra-LEAF? (Low Endotoxin, Azide-Free) antibody was purified by affinity chromatography.
- Concentration
- The antibody is bottled at the concentration indicated on the vial, typically between 2 mg/mL and 3 mg/mL. Older lots may have also been bottled at 1 mg/mL. To obtain lot-specific concentration, please enter the lot number in our Concentration and Expiration Lookup or Certificate of Analysis online tools.
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. This Ultra-LEAF? solution contains no preservative; handle under aseptic conditions.
- Application
-
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 ≤ 2.0 ?g per million cells in 100 ?l volume or 100 ?l of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
The OKT3 monoclonal antibody reacts with an epitope on the epsilon-subunit within the human CD3 complex.
Clone OKT3 can block the binding of clones SK7 and UCHT1.4 The OKT3 antibody is able to induce T cell activation. Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen sections and activation of T cells. The LEAF? purified antibody (Endotoxin <0.1 EU/?g, Azide-Free, 0.2 ?m filtered) is recommended for functional assays (Cat. No. 317304). For highly sensitive assays, we recommend Ultra-LEAF? purified antibody (Cat. No. 317326) with a lower endotoxin limit than standard LEAF? purified antibodies (Endotoxin <0.01 EU/?g).- Application References
