PCR Primed To Spur Chain Of Applications
Holly Ahern | Jun 25, 1995 | 10+ min read
What would you do if your research interests revolved around obtaining DNA from a bacterium preserved for millions of years in the gut of a bee stuck in amber, matching up a murderer to crime- scene blood half a century old, or cloning genes from a 1,000- year-old mummy? Most scientists would first consider PCR--the polymerase chain reaction--as a technique for approaching problems such as these. With PCR, minute quantities of nucleic acids can be amplified millions of times into sufficient qua

Viruses, Diseases Author: Karen Young Kreeger Sidebar: Professional Resources for Viral Disease Researchers In the mid- to late 1980s, numerous correlations were discovered between viruses and various types of cancers. For example, Epstein-Barr virus was associated with nasopharyngeal carcinoma and B-cell lymphoma, hepatitis B virus with liver cancer, and human papillomavirus with cervical cancer. Now, a decade later, basic and clinical scientists are finding out that viruses may also play a r

Virus-Disease Links Are Hard to Forge Researchers confront skepticism, conflicting results, limited funding By Douglas Steinberg If genomics is glitzy nowadays, virus research is, well, gritty. Its latest heyday, when HIV was shown to cause AIDS, only masked its true nature. Associating viruses with diseases has always been particularly difficult and labor intensive. Cause-and-effect relationships are maddeningly elusive.1 Consider the following two questions: Does infection by mouse mammary
Going Their Separate Ways: A Profile of Products for Cell Separation

Date: September 13, 1999Cell Separation Products Magnetic Cell Separation Technologies that isolate rare cell types to high purity are essential to the cell biology researcher. Understanding cell developmental pathways becomes increasingly significant as diagnosis and treatment of disease turns more to the molecular level.1 This diagnosis of cell-related diseases requires methods for detection, isolation, and analysis of individual cells regardless of their frequency.2 The hematopoietic system
