Fluorescence-Activated Cell Sorter
Jeffrey Perkel | Jul 18, 2004 | 2 min read
Nearly 35 years since Stanford researcher Leonard Herzenberg and colleagues developed the first fluorescence activated cell sorter (FACS), the instrument has become the immunologists' key tool. Immunology journals are chock-full of flow-cytometry profiles, the characteristic plots that such instruments produce.But cytometry is just half the story. The instruments also allow researchers to purify specific cell populations based on the presence or absence of particular characteristics. And therein
Immunoassay Techniques Proven To Be Outstanding In Several Fields
Holly Ahern | Oct 1, 1995 | 10 min read
SIDEBAR: Selected Suppliers of Immunoassays and Assay Systems Immunoassays combine principles of immunology and chemistry into tests that are used by scientists in practically every discipline, including fields as diverse as molecular biology and environmental science. In research applications, immunoassays such as immunoblotting (detecting membrane-bound proteins), immunohistochemistry (cell or tissue staining), and enzyme immunoassays provide a sensitive and specific means of detecting targe
Escaping the Heat

Nonradioactive Kinase Assay Kits Safety concerns and economic considerations have fueled a growing trend in the biomedical sciences: to shun the use of radioactivity when practical. Nonradioactive options for numerous applications have become widely available, including a number of nonradioactive kinase assay kits. Assays from different manufacturers employ a wide range of strategies. Most of these kits utilize antibodies, but two nonimmunochemical approaches use fluorescently tagged substrates
How Some Vaccines Protect Against More than Their Targets
Shawna Williams | Nov 1, 2020 | 10+ min read
As researchers test existing vaccines for nonspecific protection against COVID-19, immunologists are working to understand how some inoculations protect against pathogens they weren’t designed to fend off.
Bioterrorism Research: New Money, New Anxieties
John Dudley Miller | Apr 6, 2003 | 8 min read
Ned Shaw US scientists have reason to feel both heady and scared. The federal government recently released unprecedented billions of dollars to fund bioterrorism research. Yet, the merits of this sudden shift in focus are being debated, and some worry that the money will be squandered or wasted. "I have been really very upset by the focus on bioterrorism," says Stanley Falkow, professor of microbiology and immunology and of medicine at Stanford University. "Everybody's talking about it, but th
Flow Cytometry: It's Not Just For Immunologists Anymore
James Kling | Jun 22, 1997 | 9 min read
A low-profile child of the '60s, flow cytometry didn't capture the imagination of most researchers until the early 1980s. The decade saw the birth of the AIDS epidemic, and as attention focused on HIV, researchers needed a method to accurately and reproducibly characterize immune cells. Flow cytometry was suddenly thrust into the spotlight.
