The syntaxin 4A (placental) ELISA kits listed below utilize specific antibodies for the plate-based assay of syntaxin 4A (placental) in various samples. syntaxin 4A (placental) is another term for the STX4 gene, which encodes the protein, syntaxin 4 in humans. It has been reported that syntaxin 4A (placental) plays a role in the response to oxidative stress and exocytosis, among other functions. Structurally, the STX4 protein is 297 amino acid residues in length and 34.2 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is reported to be expressed in neutrophils and neutrophil-differentiated HL-60 cells. Other names for this target antigen include STX4A, p35-2, and renal carcinoma antigen NY-REN-31.
