Bcl-6 Antibody Staining Protocol for Immunohistochemistry


Description: Bcl6 is a proto-oncogene that encodes Kruppel type Zinc finger protein of 95 kDa and shares homology with transcription factor. Bcl6 is mainly expressed in normal germinal center B cells and related lymphomas. Bcl6 plays an important role in the regulation of the Th2 inflammatory response. Mice deficient in Bcl6 can develop severe Th2-type inflammation in multiple organs. This antibody reacts with Bcl-6 gene product in follicular lymphomas, diffuse large B cell lymphomas, Burkitt's lymphomas and in nodular, lymphocyte predominant Hodgkin's disease.

Additional Information:
Tissue Type: Tonsil, follicular lymphomas
Fixation: Formalin-fixed paraffin sections, or acetone fixed frozen sections
Positive Control: Tonsil, follicular lymphomas
Negative Control: Omit primary antibody, isotype control, absorption control
Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary


There is no need to perform antigen retrieval on acetone fixed frozen sections
