Simple technique for RNA purification from mouse inner ear hair cells.

Obtaining a good quality of RNA from small population of cells remain an issue. Isolation for a special anatomic location such as inner ear placed in the temporal bone become a challenge, especially in terms of time needed for isolation of living tissue from the bone, which is a key factor to preserve the RNA. Due to limited accessibility to the technologies such as laser dissection, we present a simplified procedure for isolation of good quality of RNA from the inner ear for further studies.
