Elongation factor Tu (EF-Tu) is a 43kD multifunctional protein present in Escherichia coli. 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. Monoclonal antibody 900 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. Applications: Suitable for use in ELISA, Immunofluorescence and Western Blot. Other applications have not been tested. Recommended Dilutions: Western Blot: 1:50 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
