Human TNF-alpha ELISA Kit Vertical Flow Surface functionality: NHS-ester (~ 1Product overview: Tumor Necrosis Factor alpha (TNF alpha) is a pleiotropic proinflammatory cytokine within the TNF superfamily. The biologically active form of TNF alpha exists as a homotrimer with a molecular mass of 52 kDa, whereas the monomeric form is not biologically active. In humans, TNF alpha is synthesized as a transmembrane protein and assembled intracellularly to form the noncovalently linked homotrimer, which is then expressed on the cell
