CD24 Antibody Staining Protocol for Immunohistochemistry
Description: CD24 is a 35-45 kDa GPI-linked membrane sialoglycoprotein that is expressed on pro-B, pre-B, and mature B cells, and its expression is decreased after B cell activation. CD24 is also found on granulocytes and a small fraction of thymoctes and neuroblastomas, but not on plasma cells. CD24 may play a role in the regulation of B cell proliferation and differentiation.

Additional Information:
| Species Reactivity: Human, rat |
| Fixation: Formalin fixed paraffin sections. |
| Positive Control: Spleen, lymphocytes |
| 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 |
