A method is described for the dissection of single outer hair cells in the freeze-dried state. The average dry weight of outer hair cells from the third and fourth cochlear turn in the guinea pig is of the order of one nanogram, with variations depending upon the precise location. The measured dry weight is in line with the wet weight estimated from the volume of living outer hair cells maintained under iso-osmotic conditions. The lipid fraction of outer hair cells amounts to about 21 percent of the dry weight. Average ATP levels in outer hair cells of the upper two turns range between 12-15 mmoles/kg dry weight, with no significant difference between rows or turns.
