Images & Validation

• Tested Applications: IHC
• Dilution Range: 1:100-1:200
• Reactivity: Human
• Application Notes:
  Positive Control: Tonsil: A moderate to strong membranous CD4 immunostaining should be seen in a subset of T-lymphocytes which is predominantly located in the interfollicular area. Macrophages in the germinal centres should show a moderate CD4 positivity. Liver: Kupffer cells and endothelial cells in the liver sinusoids must show at least a moderate CD4 staining. Negative Control: Tonsil: B-cells and epithelial cells must not show any CD4 staining. Liver: Hepatocytes must not show any CD4 staining. Cellular Localization: Cell surface Protocol Recommendations: Manual Protocol: Freshly cut sections should be used (less than 10 days between cutting and staining). Heat-induced antigen retrieval for 5 minutes in an autoclave at 121°C in pH 7.8 Target Retrieval Solution buffer. Apply the antibody at a dilution of 1:150 at 37°C for 60 minutes. Visualization of bound antibody by the EnVision Kit (Dako, Agilent) according to the manufacturer’s directions.

Alternative Names

L3T4; Leu3; Ly-4; Lymphocyte antigen CD4; p55; T cell antigen T4/LEU3; T cell differentiation antigen L3T4; T-cell surface antigen T4/Leu-3; T-cell surface glycoprotein CD4

In tonsil tissue a strong CD4 immunostaining is seen in a fraction of T cells and in Langerhans cells of the tonsil surface epithelium. Epithelial cells are negative.

Liver - Endothelial CD4 positivity occurs at moderate intensity in liver sinusoids.

B CLL containing numerous CD4 positive lymphocytes.
