- Product Information
In Vitro Diagnostic (IVD). Use in immunohistochemistry (IHC) test methods only.
The monoclonal antibody OSCAR is used for the in vitro examination of human biological samples using immunohistochemistry (IHC) methods for the qualitative identification of Cytokeratin. The clinical interpretation of any staining or its absence should be complemented by morphological studies and proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.
- This antibody was developed using a crude cytokeratin extract prepared from RT-4 and MCF-7 cells.
- Phosphate-buffered solution with BSA + 0.1% NaN3.
- The antibody was purified by affinity chromatography.
- Storage & Handling
- Store between 2°C and 8°C.
- Recommended Usage
Each lot of this antibody is quality control tested by immunohistochemical staining.
The optimal working dilution should be determined for each specific assay condition.
• IHC: ≥1:40 (concentrated format) with Biotin based detection systems such as USA Ultra Streptavidin Detection (Cat. No. 929501).
Positive tissue (human): Skin, Liver, Bladder, Breast
Tissue Sections: Formalin-fixed, paraffin-embedded tissues, frozen sections
Pretreatment: For optimal staining, the sections should be pretreated with an antigen unmasking solution such as citrate buffer retrieval solution (Cat. No. 928502).
Incubation: 20 minutes at room temperature
