An IgG1 monoclonal antibody (mAb 54G8) which binds to both Bordetella pertussis chaperonin-60 (cpn60) and Escherichia coli cpn60 (GroEL) was produced. mAb 54G8 as well as Fab fragments prepared from this antibody were found to abolish the ability of chaperonin-10 (cpn10, GroES) to inhibit the ATPase activity of both B. pertussis cpn60 and E. coli cpn60. Electron microscopy was used to localize ...

Hybridoma clone C3A8 was established as a result of fusion between the lymphocytes of Balb/c mice immunized with the MCF-7 breast carcinoma cell line and Sp2/0-Ag14 myeloma cells. The clone was secreted the monoclonal antibodies (Mab) either in culture supernatant or ascites fluid and still have a contaminants which need to be purify in order to get the desired antibody. The main objective of t...

We produced a monoclonal antibody (MAb) to Ureaplasma urealyticum Vancouver, the serotype 9 standard strain. By immunoblotting, this MAb showed a single, 85-kDa band with the homologous serotype and a minor, 100-kDa band with serotype 2 but did not react with any other serotype standard strain. Clinical isolates of U. urealyticum were tested with this MAb and with two sets of polyclonal antiser...

The role of monoclonal antibody (mAb) therapies in treating medical conditions has expanded tremendously since its inception in the 1970s, and their use in neurologic conditions has increased in just the past few years. Currently, mAb treatments are being tested in conditions ranging from neuromuscular disorders to demyelinating diseases. What is now considered experimental therapy may soon bec...

The purpose of this study was to evaluate the performance of a herpes simplex virus (HSV) type 1-specific anti-glycoprotein C-1 monoclonal antibody (MAb) and a type 2-specific anti-glycoprotein G-2 MAb for typing of 2,400 clinical HSV-1 isolates and 2,400 clinical HSV-2 isolates, respectively, using an enzyme immunoassay. The anti-HSV-1 MAb showed sensitivity and specificity of 100%, and the an...

BACKGROUND Ferritin is an iron storage protein, which plays a key role in iron metabolism. Measurement of ferritin level in serum is one of the most useful indicators of iron status and also a sensitive measurement of iron deficiency. Monoclonal antibodies may be useful as a tool in various aspects of ferritin investigations. In this paper, the production of a murine monoclonal antibody (mAb) a...

The negative effects of environmental estrogens on wildlife and human beings are gaining increasing attention. Research the highly sensitive detection method for Vitellogenin (Vtg), one biomarkers (EEs), is expected to detect weak in complex environments. This study aimed develop a label-free immunosensor with high specificity sensitivity testing Vtg. Carbon quantum dots (CQDs) fluorescence exc...

Among the monoclonal antibodies (Mab) against rabbit plasma cholesteryl ester transfer protein (CETP), Mab 14-8F cross-reacted with human CETP and selectively inhibited triglyceride transfer but not cholesteryl ester transfer (Ko, K. W. S., T. Ohnishi, and S. Yokoyama. 1994. J. Biol. Chem. 269: 28206;-28213). The epitope of this antibody was studied by using synthetic fragment peptides of rabbi...

Monoclonal antibody (mAb) 5C3 directed against human p140 TrkA is a structural and functional mimic of nerve growth factor (NGF) and an artificial receptor agonist. mAb 5C3 binds in the NGF-docking site and, like NGF, it promotes TrkA internalization, TrkA and phosphatidylinositol-3 kinase tyrosine phosphorylation, and increased transformation of TrkA-expressing fibroblasts. More important, mAb...

A monoclonal antibody (mab) against the antimicrobial sulfamethazine was prepared and characterized by an indirect competitive enzyme-linked immunosorbent assay (IC-ELISA). Sulfamethazine in the range of 0.2 and 45 ng/ml could be determined with the mab by IC-ELISA. cDNAs encoding a variable heavy chain and variable light chain of the mab were cloned to produce recombinant antibodies using phag...
