The TH1 ELISA kits listed below utilize specific antibodies for the plate-based assay of TH1 in various samples. TH1 is another term for the NELFCD gene, which encodes the protein, negative elongation factor complex member C/D in humans. The target protein is an important component of the NELF complex, a complex that negatively regulates the elongation of transcription by RNA polymerase II. Structurally, the NELFCD protein is described to be 590 amino acid residues in length and 66.2 kilodaltons in mass. It is localized to the nucleus of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. Other names for this target antigen include HSPC130, NELF-C, and NELF-D.
