Immunohistochemistry: CD4 Antibody - BSA Free [NBP1-19371]
Immunohistochemistry: CD4 Antibody [NBP1-19371] - Increased CD3+ and CD4+ T-cell occurrence in the brainstem of SHR-72 transgenic rat model for tauopathies. (A-D) Immunofluorescence staining showed CD4+ T-cells in SHR-72 transgenic animals. (E- H) Immunofluorescence staining showed more perivascular than brain parenchyma infiltrating CD4+ T-cells in SHR-72 transgenic animals.

Application Notes
This CD4 antibody is useful for ICC, Western Blot, and IHC-paraffin embedded sections. In WB, a band is seen ~45 kDa. In ICC/IF, membrane staining was observed in human brain cells. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended. In ICC/IF, membrane staining was observed in Jurkat cells.
In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue.

Background: CD4
Given its critical role in T cell development, CD4 also has diverse immunology-related functions. CD4 acts as a coreceptor with the T-cell receptor (TCR) during T cell activation and thymic differentiation by binding directly to major histocompatibility complex (MHC) class II antigens and associating with the protein tyrosine kinase, Lck (4). This interaction contributes to the formation of the immunological synapse (5). Defects in antigen presentation cause dysfunction of CD4+ T cells and the almost complete loss of MHC II expression on B cells in peripheral blood, as observed in severe combined immunodeficiency (SCID) (6). CD4 also functions as a receptor for the human immunodeficiency virus (HIV) by binding to gp120, the envelope glycoprotein of HIV-1. It has been shown that the V-like domains are critical for binding to gp120 (7). In immune mediated and infectious diseases of the central nervous system, CD4 functions as an indirect mediator of neuronal damage (8).
