Monoclonal Mouse Anti-Human
CD4
Clone 4B12
CD4 is a transmembrane glycoprotein, expressed on normal thymocytes, T-helper cells, majority of mature peripheral T cells, and a subset of suppressor or cytotoxic T cells.
CD4 is not found on immature thymocytes. The antibody is useful for the identification of anaplastic large cell lymphomas, unspecified peripheral T-cell lymphomas and mycosis fungoides.
Peripheral T-cell lymphoma (FFPE) stained wit FLEX Anti-CD4, Code IR649/IS649.
Peripheral T-cell lymphoma. The majority of the neoplastic cells show a strong distinct membranous staining reaction.
Clinical application for IR649/IS649. For identification of thymocytes, T-helper cells and related tumors such as peripheral T-cell lymphoma (unspecified), anaplastic large cell lymphoma and mycosis fungoides.
Disclaimer: Due to variances among color computer monitors, the colors you see on your screen may not be the exact colors of the stain. The image you see should be considered close renditions to the actual stain.
- Optimized staining performance of both high- and low-expression structures
- Crisp and clear staining with no background
- Optimal laboratory efficiency with ready-to-use antibodies on Dako Autostainer Plus
FLEX Monoclonal Mouse Anti-Human CD4, Clone 4B12, Ready-to-Use (Dako Autostainer/Autostainer Plus), is intended for use in immunohistochemistry together with Dako Autostainer/Autostainer Plus instruments. This antibody labels thymocytes and T-helper cells (1) and the antibody is useful for the identification of anaplastic large cell lymphomas (2). Antibodies to CD4 may also be useful for the identification of mycosis fungoides and unspecified peripheral T-cell lymphoma (3-5). The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.
