Western blotting analysis using CD4 antibody (Cat#H1150). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with CD4 antibody (Cat#H1150, 1:2,500) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
Immunohistochemistry was performed on paraffin-embedded human tonsillitis using glial fibrillary acidic protein antibody (Cat#H1150, 1:500). Antigen retrieval was done in sodium citrate buffer (pH 6.0). DAB was used for detection, with hematoxylin counterstaining. Images were acquired using a Nikon Ci-L Plus microscope (40× objective). Scale bar: 25 μm.
Immunocytochemical staining shows negative staining in paraffin-embedded human cerebral cortex. CD4 antibody (Cat#H1150) was used at 1:500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with Immunocytochemical staining protocol.
Immunocytochemical staining shows positive staining in paraffin-embedded human cervical squamous cell carcinoma. CD4 antibody (Cat#H1150) was used at 1:500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with Immunocytochemical staining protocol.
Immunocytochemical staining shows positive staining in paraffin-embedded human liver. CD4 antibody (Cat#H1150) was used at 1:500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with Immunocytochemical staining protocol.
Immunocytochemical staining shows positive staining in paraffin-embedded human spleen. CD4 antibody (Cat#H1150) was used at 1:500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with Immunocytochemical staining protocol.
Immunocytochemical staining shows positive staining in paraffin-embedded human tonsil. CD4 antibody (Cat#H1150) was used at 1:500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with Immunocytochemical staining protocol.
Immunocytochemical staining shows positive staining in paraffin-embedded human thymus. CD4 antibody (Cat#H1150) was used at 1:500 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with Immunocytochemical staining protocol.
