BM2 (Myeloid Marker) Antibody Staining Protocol for Immunohistochemistry
Description: NCL-BM2 is reactive with a cytoplasmic antigen expressed in human granulocytes. Markers of myeloid cells are useful in the identification of different levels of cellular differentiation. NCL-BM1 and NCL-BM2 are reported to react with early precursor and mature forms of human myeloid cells.

Additional Information:
| Tissue Type: Blood or bone marrow |
| Fixation: Formalin-fixed paraffin sections, or acetone fixed frozen sections |
| Positive Control: Blood or bone marrow |
| 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 |
Notes:
There is no need to perform antigen retrieval on acetone fixed frozen sections |
