No it is not real.
The name of the lab in "Amazing Spider-Man" that Norman Osborn owns is Oscorp however the full name is Oscorp Industries.
Of course, the Willis tower is in real life.
Yes.
no, oscorp is a fictional company founded by the fictional character Norman Osborn within the marvel comic book series The Amazing Spider-Man. Also if this is in reference to the experiments done at "oscorp" in the most recent Spider-Man movie, that is not an accurate depiction of the events that occurred in the actual Spider-Man comics. However more to the point, similar studies are done in real life in the field of genetics, in fact the gene that allows jelly fish to glow has been successfully implanted in mice at one point. Not that I'm saying to worry about rampaging lizard-men, as that is not very likely, just for the record.
In the story, the Tower was the glamorous Hollywood Tower Hotel. In real life it never was or is planned to be a real hotel.
