Specificité
Human PAPP-A antigen purified from placental blood (heterotetrameric complex, consisting of PAPP-A subunits and pro-MBP subunits). MAbs 11E4 and 5H9 are specific to proMBP subunit. IgG for MAb 11E4 IgG2a for MAbs 4G11, 10A5, 3C8, 10H9, 18A10 and 7A6 IgG2b for MAbs 5H9, 10E1 and 10E2
htPAPP-A and dPAPP-A (PAPP-A dimer) immunoassays and immunoprecipitation. Recommended pairs for the detection of dPAPP-A antigen in blood of AMI patients and patients with unstable angina (coating - conjugate): 4G11 – 3C8 4G11 – 10H9 10E1 – 7A6 Best pairs for the detection of htPAPP-A antigen in pregnancy serum (coating - conjugate): 4G11 – 3C8 4G11 – 10H9 10E2 – 10E1 10E2 – 5H9 5H9 – 10E2 10E1 – 7A6 PAPP-A immunodetection in Western blotting. MAb 18A10 recognizes PAPP-A subunit in reducing and non-reducing conditions after antigen transfer onto nitrocellulose membrane after SDS-gel electrophoresis. MAbs 4G11, 10A5, 18A10 and 10E1 recognize htPAPP-A, consisting of PAPP-A subunits and proMBP subunits, in non-reducing conditions.
