CD4 Antibody (755-2444-82) in IHC (P)
Immunohistochemical analysis of CD4 was performed on formalin-fixed paraffin-embedded human tonsil tissue. To expose the target protein, HIER was performed on de-paraffinized sections using BOND Epitope Retrieval Solution 2 (pH 9) for 30 minutes, followed by a 5-min cool down and a 5-min wash with ddH2O. Tissues were permeabilized with 0.1% Triton X-100 in 1X PBS for 30 mins and blocked with 3% BSA/5% norma... View More

Product Specific Information
Description: The N1UG0 monoclonal antibody reacts with human CD4, a 59 kDa cell surface glycoprotein expressed by the majority of thymocytes, a subpopulation of mature T cells (T-helper cells) and in low levels on monocytes. CD4 is a receptor for the human immunodeficiency virus (HIV). The N1UG0 antibody is recommended for use in staining human formalin-fixed paraffin embedded tissue sections.
Applications Reported: This N1UG0 antibody has been reported for use in flow cytometric analysis, western blotting, and immunohistochemical staining of formalin-fixed paraffin embedded tissue sections.
Applications Tested: This N1UG0 antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded human tissue using high pH antigen retrieval and can be used at 20 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining.
Target Information
The CD4 antigen is involved in the recognition of MHC class II molecules and is a co-receptor for HIV. CD4 is primarily expressed in a subset of T-lymphocytes, also referred to as T helper cells, but may also be expressed by other cells in the immune system, such as monocytes, macrophages, and dendritic cells. At the tissue level, CD4 expression may be detected in thymus, lymph nodes, tonsils, and spleen, and also in specific regions of the brain, gut, and other non-lymphoid tissues. CD4 functions to initiate or augment the early phase of T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase, Lck. It may also function as an important mediator of direct neuronal damage in infectious and immune-mediated diseases of the central nervous system. Multiple alternatively spliced transcripts have been identified in this gene [RefSeq, July 2017].
