Modular steel construction (MSC) consists of the off-site prefabrication a fully finished module and on-site assembling unit. The popularity MSC is on rise, attributable to its technical advantages speed quality buildings with repetitive units. Inter-module connection critical for overall stability load-bearing capacity MSC. An innovative, prefabricated liftable (FPLC) using standard corner fit...

A soluble fructose-1,6-bisphosphate aldolase enzyme has been purified 50.2-fold (2.36%) at the homogeneity from the electric organ of Electrophorus electricus by one step of DEAE-52 anion exchange chromatography followed by Superose-12 gel filtration-FPLC. Like other aldolase enzymes the E. electricus protein is a dimer with two identical subunits of 45 kDa. The N-terminal (20 residues) reveale...

The two 4.6 kb chloramphenicol resistance (CmR) plasmids pSCS6 and pSCS7, previously identified in Staphylococcus aureus from subclinical bovine mastitis, both encoded an inducible chloramphenicol acetyltransferase (CAT, EC 2.3.1.28). The pSCS6- and pSCS7-encoded CAT variants were purified by ammonium sulphate precipitation, ion-exchange chromatography and fast protein liquid chromatography (FP...
