Core Day showcases expert scientific support for NIEHS researchers

At the annual NIEHS Core Day, representatives from core labs updated attendees on the broad range of scientific services and resources available.

During the annual NIEHS Core Day, 43 presenters of 23 different support groups at NIEHS exhibited posters, talked to researchers, and promoted the broad range of scientific services and resources available at the institute. Core labs provide specialized equipment, techniques, and expertise to in-house, or intramural, scientists.

“The goal of Core Day is to provide information to intramural researchers on the best and most modern technologies and techniques available through NIEHS Core Facilities,” explained Robert Petrovich, Ph.D., organizer of the Nov. 27 event and director of the Protein Expression Core Facility.

Resources available to NIEHS researchers

Trainees, lead researchers, and other scientists from the NIEHS Division of Intramural Research and the National Toxicology Program (NTP) Laboratory gathered information about the multitude of services provided by the supporting groups.

Those services range from state-of-art quality assurance and veterinary medicine, to modern and innovative technologies such as cryo-electron microscopy, multiphoton microscopy, mass cytometry, and next-generation sequencing. “Today, I learned about different Core Facilities, new techniques, and interesting services that I could use on my research,” said Priya Halvorsen, Ph.D., a postdoctoral fellow from the Immunogenetics Group.

Partnerships for science development

Representatives of the supporting groups were also excited to present recent updates on their facilities and services, such as the modernizations implemented in animal husbandry. Attendees were also able to troubleshoot their new experiments, especially those using recently developed techniques, such as CRISPR technology and in vivo imaging. “The core facilities are operated by experts, and they are committed to the development of the research at NIEHS,” Petrovich said.

Jean Harry, Ph.D., head of the NTP Neurotoxicology Group, agreed. “The services provided by the different core facilities give researchers at NIEHS extensive capabilities to perform cutting-edge research.”
