Abstract: | NGC 4485 is a late-type galaxy moving through the very extended HI envelope of its companion, NGC 4490. NGC 4485 is undetected
in HI,CO and IRAS wavebands, but a peak at all of these frequencies is seen displaced from the optical disk. HI data show
a prominent bow-shock ahead of this displaced gas. It is argued that almost the entire ISM, including molecular clouds, has
been stripped from this galaxy byram-pressure, and that it will emerge from the encounter with very little star forming potential.
