PADI4 is a member of a gene family which encodes enzymes responsible for the conversion of arginine residues to citrulline residues. This gene may play a role in granulocyte and macrophage development leading to inflammation and immune response.The deduced 663-amino acid protein, approximately 50% identical to rat PAD types I, II, and III and 73% identical with rat keratinocyte PAD IV, is most conserved in the C terminal two-thirds of the sequence. Functional analysis indicated that the recombinant protein is fully active against arginine-containing substrates. Western blot analysis showed that expression of a 67-kD protein is induced by incubation of HL60 cells with differentiation factors.
Human Protein-arginine deiminase type-4 antibody (PADI4-Ab) ELISA Kit employs a two-site sandwich ELISA to quantitate PADI4-Ab in samples. An antibody specific for PADI4-Ab has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPADI4-Ab present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PADI4-Ab is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PADI4-Ab bound in the initial step. The color development is stopped and the intensity of the color is measured.
