Specificity
The monoclonal antibody 900 recognizes elongation factor Tu (EF-Tu), a 43 kDa multifunctional protein present in Escherichia coli. The antibody recognizes EF-Tu in organisms belonging to bacterial and archaeal domains, yet no organisms from the eukaryotic domain. The panbacterial distribution of EF-Tu, which is present in large amounts in every prokaryotic cell, renders this protein a good candidate for diagnostic purposes. The highly conserved epitope recognized by monoclonal antibody 900 is located at the very end of the N-terminus of the EF-Tu molecule (SKEKFE).
Cross-Reactivity (Details)
Species reactivity (tested):E. coli. Cross react with Bacteroides fragilis, Streptococcus oralis, Bacillus subtilis, Pseudomonas aeruginosa, Burkholderia cepacia, and Deinococcus sp., weakly cross reacts with Mycobacterium tuberculosis.
EF-Tu is one of the most abundant proteins present in prokaryotes, representing about 5 % of the total cellular protein of E. coli. During protein biosynthesis, the elongation process, EF-Tu catalyzes the binding of each aminoacyl-tRNA to the ribosome. It also interacts with several macromolecules and guanine nucleotides, including EF-Ts, GDP, GTP, and some ribosomal proteins.Synonyms: CCS-3, CCS3, EEF1A, EF-1-alpha-1, EF-Tu, EF1A, Elongation factor 1 alpha 1, Elongation factor Tu, Eukaryotic elongation factor 1 A-1, FLJ25721, GRAF-1EF, Leukocyte receptor cluster member 7, PTI1, eEF1A-1
