Abcam, ab183685, Anti-CD4 antibody [EPR19514]

Size: 20µL / 100µL / 1mL
Anti-CD4 antibody [EPR19514] (ab183685) is a rabbit monoclonal antibody detecting CD4 in Western Blot, IP, IHC-P, IHC-Fr. Suitable for Mouse. - Biophysical QC for unrivalled batch-batch consistency - Over 350 publications IL-4 plays a key role in immunology by promoting the differentiation of naïve T cells into Th2 cells, which are essential for humoral immunity. It also stimulates B cell proliferation and antibody class switching, particularly toward IgE, contributing to allergic and anti-parasitic responses. IL-4 also plays a role in conditions like systemic lupus erythematosus (SLE) and multiple sclerosis, where it influences immune responses and inflammation.
