Putting a reversed power supply across an op-amp is a great way to kill it quick. I've had chips survive this for a few seconds, but more often than not they die instantly.

If you've got an extra op-amp or a TLE2426 and a few common DIYing parts, you could build my simple op-amp testing circuit to find out if your chip is dead.
