PROTEASE ENHANCER - (May/30/2008 )

IS THERE ANY ONE WHO CAN HELP ME?
I HAVE TO ACTIVATE OR ENHANCE DIFFERENT TYPES OF PROTEASES EXPRESSION ON 293-EBNA CELLS (A HUMAN EMBRIONAL KIDNEY CELL LINE).
I READ SOME PAPERS AND FOUND THAT SOME IONS CONCENTRATIONS SUCH AS CA2+ OR MG2+ MAY IMPROVE PROTEASES EXPRESSION. IS THERE ANY MOLECULE THAT ACTIVATES PROTEASES EXPRESSION?

have you checked biotech company websites? sometimes they are better help than waiting for people to reply! go for those who produce PROTEASE INHIBITORS, such as ROCHE, PIERCE, INVITROGEN, etc......maybe they have ENHANCER as well.
