Mac-Mod Vydac 218TP C18, 300 A, 12 um, 10.0 x 10 mm Prep Cartridge
Vydac TP was the first range of wide pore media phases developed and became the industry standard for peptide and protein separations. The 300 TP silica gives polypeptide molecules complete access to the interior of the silica pores. Vydac TP is known for long column lifetime and negligible phase leaching. Vydac TP provides reliable protein purifications, scalable from analytical to preparative scale. Vydac 218TP and 238TP are used for small polypeptides of 4-5kDa, enzymatic digest fragments, natural and synthetic peptides and multi-ring compounds. Vydac 208TP is recommended for polypeptides of molecular weight 10-20kDa. Vydac 214TP is recommended for the analysis of glycoproteins, hemoglobin variants, histones, insulin variants and membrane proteins. Vydac 219TP is suitable for polypeptides with aromatic side chains, large hydrophobic proteins, membrane-spanning peptides, lipid peptides and fusion proteins from inclusion bodies.
