Dear all, Arginine sepharose 4B is an affinity column. If you have used it please let me know where you purchased it.
GE Lifesciences used to sell it but discontinued it. I found it in China in the site http://www.pharmaceutical-sales.net and I corresponded with their sales representative Does anyone know this company? Are their products reliable? It is the only place I found this product. I would appreciate any information about this company or any place that may sell arg sepharose. Thank you. Jackie Vitali
