Profile: Pro-Chem Inc. deals with rapid protein purification kits, provac vacuum kits and static protein concentrators. Our rapid protein purification kits include spin column kits and vacuum kits. Our spin column kits are supplied with affinity and single step spin columns, unambiguous protocols, desalting/buffer exchange columns & ready-to-use buffers. Our provac vacuum kits are used to produce monoclonal antibodies from hybridomas on a laboratory scale. The hydrophobic surface of tissue culture flasks (T flasks) and cell culture dishes is ideal for stationary culture of hybridomas clones. T flasks vary in size from 12.5 cm2 to 300 cm2 with working volumes between 5 and 400 ml. We use vacuum as the driving force. It permits large volumes of dilute samples to be loaded on to the columns without the need of a centrifuge.
