CD16 Antibody Staining Protocol for Immunohistochemistry
Description: CD16 is a low affinity Fc receptor of complexed IgG, Fc/gamma RIII and expressed on NK cells, granulocytoes, activated macrophages and a subset of T cells. CD16 exists both as a glycosyl-phosphatidylinositol-anchored protein in polymorphonuclear cells and as a transmembrane protein in NK cells. This antigen will help detect CD16 and NK cells in a variety of tissues.

Counterstain
| Reagent: Mayer's Hematoxylin |
| Staining Time: 30 seconds |
Results:
| Staining Pattern: Membrane staining of macrophage, neutrophils, NK cells and granulocytes |
| Images: Search image |
Additional Information:
| Tissue Type: Tonsil |
| Fixation: Formalin fixed paraffin sections |
| Positive Control: Tonsil |
| Negative Control: Omit primary antibody, isotype control or 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:
|
Not effective on fixed frozen sections |
