Monoclonal Mouse Anti-Human
BCL6 Protein
Clone PG-B6p
The BCL6 gene encodes a 706 amino acid nuclear protein of the Kruppel-type zinc finger protein.
It is rearranged in about 30% of diffuse large B-cell lymphomas, and is expressed predominantly in normal germinal centre B cells and related lymphomas (1). The antibody gives a strong nuclear labeling of BCL6 protein in follicular lymphomas, diffuse large B-cell lymphomas, Burkitt's lymphomas, and nodular, lymphocyte-predominance Hodgkin's disease. The PG-B6p antibody is useful for differentiating proliferation centres in B-CLL (BCL2+/BCL6-) from trapped germinal centres (BCL2-/BCL6+) in mantle cell lymphomas, and for identifying neoplastic cells in cases of nodular, lymphocyte-predominance Hodgkin's disease. BCL6 protein is not expressed in B-CLL, hairy cell leukemia, mantle cell and marginal-zone derived lymphomas (2, 3).

Follicular lymphoma (FFPE) stained with FLEX Anti-BCL6 Protein, Code IR625/IS625.
Follicular lymphoma. The majority of the neoplastic cells show a distinct nuclear staining reaction.
Clinical application for IR625/IS625. For classification of diffuse large B-cell lymphomas, follicular lymphomas and Burkitt lymphoma/leukemia.
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 Link 48
FLEX Monoclonal Mouse Anti-Human BCL6 Protein, Clone PG-B6p, Ready-to-Use (Link), is intended for use in immunohistochemistry together with Autostainer Link instruments. This antibody is useful for classification of diffuse large B-cell lymphomas, follicular lymphomas and Burkitt's lymphomas (1). 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.
SDS-PAGE analysis of immunoprecipitates formed between total lysates of Bjab cells (BCL6+) and BCL6 transfected EB3 cells and the antibody, shows reaction with a ~95 kDa fragment corresponding to BCL6. No reaction is observed with Rd cells (BCL6-) and EB3 cells transfected with a control plasmid (1).
Clone: PG-B6p (1). Isotype: IgG1, kappa.
