Contamination Removal Systems

Removal of interfering agents such as detergents, salts, dyes, and radioisotopes in an integral part of effective sample preparation.  For these purposes, G-Biosciences developed an array of spin columns which accomodate a variety of volumes and molecular weight ranges.  The SpinOUT™ GT-100SpinOUT™ GT-600, and SpinOUT™ GT-1200 columns are versatile, spin-format columns for the desalting and buffer exchange of peptide, protein, and nucleic acid samples ranging from 5ųL to 4mL sample volumes.  This technology is also available in a 96-well spin plate format.  Optimized for FPLC applications, the G-Trap™ line of desalting columns are ideal for buffer exchange and desalting of samples of a variety of volumes and MWCO’s.  G-Trap™ columns are available for three MWCO’s, 700Da G-Trap™ GT-100, 6kDa G-Trap™ GT-600, and 30kDa G-Trap™ GT-1200.
