Due to construction and building renovations at the Wistar Institute, the Protein Expression Facility has been relocated to the University of Pennsylvania Veterinary School, Rosenthal Building (corner of 38th and Spruce Streets), Rooms 426-430.  

When you enter the doors off Spruce Street, you will need to sign in with the receptionist.  After you enter the double doors, you will approach a stairwell and elevator on the right side.  Take the elevator to fourth floor.  When you come out of the stairwell/elevator, turn right.  We are located at the second door on the right.
