Narrative:

We were cleared to taxi to runway 4L, after holding short of runway 32L for departing traffic. At a point on the southwest taxiway, approximately 1000' from the departure end of runway 4L, we were cleared for takeoff with a left turn. Shortly after this the captain and I completed our before takeoff checklist. We then inadvertently passed bravo taxiway, which would have taken us to runway 4L. Instead, west/O realizing it, we continued taxiing a short distance and turned on runway 36. Still west/O realizing, we were on the wrong runway, we took off. During climb out at approximately 400' AGL, the tower controller informed us of our mistake.
