The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 64 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use at an assay dependent concentration.
ELISA titre using peptide based assay: 1/312500.
AP4 (Replication initiator 1) is a sequence-specific double-stranded DNA-binding protein required for initiation of chromosomal DNA replication. It binds on 5'-ATT-3' reiterated sequences downstream of the origin of bidirectional replication (OBR) and a second, homologous ATT sequence of opposite orientation situated within the OBR zone. AP4 facilitates DNA bending.
