Keratin 14 Antibody Staining Protocol for Immunohistochemistry
Description: Keratin 14 belongs to the type A (acidic) subfamily of low molecular weight keratins and exists in combination with keratin 5. Keratin 14 has been studied as a prognostic marker in breast cancer. This is an excellent antibody for immunohistochemical staining of formalin-fixed, paraffin-embedded tissue sections.

Additional Information:
| Tissue Type: Skin |
| Fixation: Formalin fixed paraffin sections. Not tested on frozen sections. |
| Positive Control: Skin |
| 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 |
