PISCATAWAY — Emergency responders are on the scene of a smoke-filled biology lab on Rutgers University's Piscataway campus, a university spokesman confirmed today.

The fire appears to be related to contractors working on roof renovations at Nelson Biology Laboratories on Allison Road on the Busch Campus, said Steve Manas, a Rutgers spokesman.

"Smoke got in the building," Manas said.

It is unclear if anyone was injured by the fire, campus officials said.

Nelson Biology Laboratories, located in a cluster of science buildings in the center of the Busch campus, is a multi-story brick building. It houses the Center for Alcohol Studies, Laboratory Animal Services and parts of the genetics, psychology, life science, cell biology and neuroscience, molecular biology and biochemistry departments.

Nelson is also home to one of the university's most valuable assets, the Rutgers University Cell and DNA Repository. The facility, which contains millions of DNA and cell samples, is the largest university-based collection of its kind and draws millions in grant money to Rutgers.
