- Formulation
-
test sizes: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).
µg sizes: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide. - Preparation
- The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions.
- Concentration
-
µg sizes: 0.2 mg/ml
test sizes: lot-specific (please contact technical support for concentration and total µg amount) - 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.
- Application
- Recommended Usage
-
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining using the test sizes, 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. For µg sizes, 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.

Green Laser (532 nm)/Yellow-Green Laser (561 nm) - Application Notes
-
Clone IM7 has been reported to recognize an epitope common to alloantigens and all isoforms of CD4417,18 that is located between amino acids 145 and 18620. This clone has been validated for immunocytochemistry (ICC) and frozen immunohistochemistry (IHC-F). Additional reported applications (for the relevant formats) include: immunohistochemistry of acetone-fixed frozen sections and formalin-fixed paraffin-embedded sections6,7, complement-mediated cytotoxicity1, immunoprecipitation1,3, and in vivo inhibition of DTH4,5. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for functional assays (Cat. No. 103014). For highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 103046) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin <0.01 EU/µg).
