Biopolymer separations were studied on Micropak TSK type SW columns, which contain an aqueous compatible steric exclusion support. Columns of two different pore sizes, designated 2000SW and 3000SW, were compared for separation of proteins and nucleic

Two types of high performance aqueous size exclusion columns have recently been developed, one a rigid spherical silica-based packing containing a new hydrophilic bonded phase (MicroPak TSK Gel Type SW) and the other an organic-based, semi-rigid gel

A mutant of Salmonella typhimurium has been isolated that has less than 5% of the ribonuclease activity of the parent strain. Mutant screening and enzyme assays were done in the presence of ethylenediaminetetraacetic acid, a substance that activates

Apolipoproteins, extracted from human serum high-density lipoproteins, can be resolved and recovered with high yield from a preparative MicroPak TSK Type 3000SW size-exclusion column using Tris-buffered 6 m urea or 6 m guanidinium chloride mobile pha

Size-exclusion, ion-exchange, and reversed-phase chromatography were investigated for use in purification and characterization of Staphylococcal enterotoxin B (SEB), a 28,000 Mr protein associated with Staphylococcal food-borne intoxication. In all a

The high-performance liquid chromatographic separation of a large variety of nucleic acid constituents on a silica-based, weak-anion exchange column was accomplished. Using this technique it was possible to achieve some relatively difficult separatio
