Monoclonal anti-enrofloxacin antibody was prepared for a direct competitive enzyme-linked immunosorbent assay (ELISA) and purification system using monoclonal antibody (mAb) coupled magnetic nanoparticles (MNPs). The IC50 values of the developed mAb for enrofloxacin (ENR), ciprofloxacin, difloxacin, sarafloxacin, pefloxacin, and norfloxacin were 5.0, 8.3, 9.7, 21.7, 36.0, and 63.7 ng/mL, respec...

A murine monoclonal antibody (MAb) which binds to human metastatic gastrointestinal adenocarcinomas can be administered safely and has tumor effects in some patients. Its therapeutic effect was assessed in 20 patients with measurable advanced colorectal carcinoma that was refractory to prior surgical resection, chemotherapy, and/or radiotherapy. All patients had agreed to receive no other thera...

A murine monoclonal antibody 14.18 specifically recognizes disialoganglioside GD2, the major ganglioside expressed on the surface of human neuroblastoma cells. This monoclonal antibody (Mab) is of immunoglobulin G3 isotype, has an affinity constant (KA) of 3.5 X 10(8) M-1, and reacts preferentially with tumor cells and fresh frozen tumor tissues of neuroectodermal origin in enzyme-linked immuno...

The expression of Triggering Receptor Expressed on Myeloid cells ( TREM)-1 has been described as a predictive marker for anti-Tumor Necrosis Factor (TNF)-? monoclonal antibody (mAb) therapy responsiveness in patients with inflammatory bowel disease (IBD). Here we investigated TREM-1 specifically CD14+ monocytes relation to anti-TNF response. pretreatment levels Crohn’s (CD) were outcome mAb the...

Abstract Hydrolytic degradation of the polysorbate 20 (PS20) surfactant in protein-based liquid formulations releases free fatty acids (FFAs), which can accumulate to form particles drug products during real-time (long-term) storage. To identify formulation conditions that mitigate risk particle formation, we conducted a longitudinal study using purified recombinant monoclonal antibody (mAb) fo...

immunoglobulin e is one of the five classes of immonoglobulins that plays an important role in allergic diseases. production of monoclonal antibodies by a single clonotype against different epitopes of immunoglobulin e has high priority in development of diagnostic kits. in this study, an attempt was made to produce monoclonal antibodies against human immunoglobulin e. balb/c mice were immunize...

Monoclonal antibody (mAb) therapeutics targeting cancer, autoimmune diseases, inflammatory diseases, and infectious diseases are growing exponentially. Although numerous panels of mAbs targeting infectious disease agents have been developed, their progression into clinically useful mAbs is often hindered by the lack of sequence information and/or loss of hybridoma cells that produce them. Here ...

by immunizing mice with killed whole bacterial cells of brucella abortus s (99), a panel of six hybridomas producing monoclonal antibodies (mab) specific for the surface antigens of this bacterium were produced. elisa was used to screen the hybridoma supernatants. immunoblots of the cell extract indicated that three mab were specific for s-lps (ba-1, ba-2, ba-3) and three others were reactive w...

background : production of monoclonal antibodies to leishmania antigens assists the identification and characterization of these organisms. objective: production of monoclonal antibodies against epitopes on the gp63. methods: two murine monoclonal antibodies to gp63 were produced and characterized. the reactions of both antibodies with soluble leishmanial antigens, purified gp63 and truncated r...

The viral haemorrhagic septicaemia virus (VHSV) comprises 4 major genotypes and a number of subtypes with, in most cases, distinct geographical distribution. A quick and simple detection method that can discriminate the different genotypes is desirable for a quick and more efficient prevention of the spread of genotypes to new geographical areas. A monoclonal antibody (MAb) against VHSV genotyp...
