Description

O13 detects a cell surface antigen expressed in 95% of Ewing's sarcomas (ES). The antigen is also found in some primative neuroectodermal tumors (PNET) and peripheral neuroepitheliomas (PN). Other small round cell tumors (SRCT) that are commonly included in the differential diagnosis of ES, such as neuroblastomas, lymphomas, and rhabdomyosarcomas, as well as other sarcomas, carcinomas, and neuroectodermal tumors are generally negative. In normal tissues, the antigen is strongly expressed in thymocytes and a subset of pancreatic islet cells.

This antibody is effective in immunohistochemistry (IHC).

This antibody is specific for p30/32 MIC2, a 30-32 kD glycoprotein, also referred to as the HBA71 antigen.

Concentrated Format:
Cat. No. 915601 (Formerly: SIG-3620-1000) [1 mL]

Prediluted Formats:
Cat. No. 915602 (Formerly: SIG-3620-16) [6 mL Level 1] is ready to use with automated strainers with Biotin-based detection systems such as USA Ultra Streptavidin Detection (Cat. No. 929501).

Cat. No. 915603 (Formerly: SIG-3620-26) [6 mL Level 2] is ready-to-use with Biotin-based detection systems such as USA Ultra Streptavidin Detection (Cat. No. 929501).

Product Information

Intended Use:

In Vitro Diagnostic (IVD). Use in immunohistochemistry (IHC) test methods only.

The monoclonal antibody O13 is used for the in vitro examination of human biological samples using immunohistochemistry (IHC) methods for the qualitative identification of CD99. 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.

Reactivity
Human
Immunogen
This antibody was generated against MeWo human melanoma cells.
Formulation
Phosphate-buffered solution with BSA + 0.1% NaN3.
Preparation
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) for Biotin based detection systems such as USA Ultra Streptavidin Detection (Cat. No. 929501)

Positive tissue (human): Ewing's sarcoma

Tissue Sections: Formalin-fixed, paraffin-embedded tissues
Pretreatment: For optimal staining, the sections should be pretreated with an antigen unmasking solution such as Retrieve-All 1 (Cat. No. 927901)
Incubation: 20-60 minutes at room temperature
