Antibody has been raised in rabbit against L7/L12 protein of E. coli 50S ribosomes and purified, finally through affinity column. A sensitive assay method using ELISA technique has also been standardised. LC 50S ribosomes react more with the antibody than TC 50S ribosomes. This supports the earlier physical data [Burma D P, Srivastava A K, Srivastava S, Tewari D S, Dash D & Sengupta S K, (1984), Biochem Biophys Res Commun, 124, 970] indicating that L7/L12 stalk region is protruded in medium in LC ribosomes and folded towards the body in TC ribosomes.
