Abstract: Ampicillin(Amp) was coupled to carrier proteins of bovine serum albumin(BSA) and ovalbumin(OVA) to synthetize immunogen BSA-Amp and detection antigen OVA-Amp.Four hybridoma cell lines secreting monoclonal antibodies(mAbs) specific for Amp were established by immunizing BALB/c mice with BSA-Amp using hybridoma technology.The antibody titers of mAb ascites(1G7,2A11,2D10 and 3F6) were determined as 1∶2.56×107,1∶1.28×107,1∶5.12×106 and 1∶5.12×106 in ELISA,and their half maximal inhibitory concentration(IC50) of Amp were 10.22,3.58,4.03,4.95 ng/mL in the inhibitive ELISA,respectively.The Amp mAbs showed significant cross-reactivity to the penicillin antibiotics of carbenicillin(1G7,2A11,2D10 and 3F6),penicillin G(1G7 and 3F6),and amoxicillin(1G7),whereas no obvious cross-reactivity to dicloxacillin or cloxacillin was found.
