The HBD1 ELISA kits listed below are analytical tools for measuring concentrations of HBD1 in various samples. HBD1 is an alternative name for the human DEFB1 gene, which encodes the protein, defensin beta 1. It has been mentioned that HBD1 plays a role in chemotaxis and GPCR signaling pathways, among other functions. Structurally, the DEFB1 protein is described to be 68 amino acid residues in length and 7.4 kilodaltons in mass. It is known to be a secreted protein. Other names for this target antigen include BD1, BD1, and DEFB101.
