100 micrograms per mL.
Explanation:
The PBS diluted mixture used for the standard curve measurement of protein concentration is a 1:10 dilution from the original homogenate of the protein with PBS. So, if the diluted mixture contains 10 micrograms per mL, the original homogenate contains 10x that. 10*10= 100 micrograms per mL.
