Anti-HsSwt1 antibodies are used in antigen-specific immunodetection in biological samples. The target HsSwt1 is a known alias name of the protein SWT1 RNA endoribonuclease homolog, encoded by the SWT1 gene in humans. This 900-amino acid residue protein is a member of the SWT1 protein family. In terms of tissue expression, it is noted to be expressed weakly in testis.
