Anti-SPT4 antibodies are used in antigen-specific immunodetection in biological samples. The target SPT4 is a known alias name of the protein SPT4 homolog, DSIF elongation factor subunit, encoded by the SUPT4H1 gene in humans. This 117-amino acid residue protein is a known component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates mRNA processing and transcription elongation by RNA polymerase II. It is localized to the nucleus of the cell. In terms of tissue expression, it is widely expressed across many tissue types. Other synonyms for SPT4 include SPT4H and SUPT4H. Western Blot is a widely used application for the SPT4 antibodies listed below. In addition, ELISA is also a common application.
