These 42A ELISA kits are immunodetection tools for measuring the levels of 42A in biological samples. 42A is an alias of the human S100A4 gene, which encodes the protein, S100 calcium binding protein A4. Notably, 42A is known to play a role in NF-kappaB signaling pathways, among other functions. The S100A4 protein is described to be 101 amino acid residues in length and 11.7 kilodaltons in mass. Its subcellular localization is in the nucleus, cytoplasm, and is secreted. In terms of tissue specificity, it is ubiquitously expressed across many tissue types. Other names for this target antigen include 18A2. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
