It's all about Cells
Miltenyi Biotec | Jan 12, 2009 | 2 min read
It's all about cells Miltenyi Biotec products and services benefit the biomedical research community worldwide In 1989, a success story began in Bergisch Gladbach near Cologne: MACS® Technology was developed, an efficient and reliable method to tag and separate cells magnetically. Since then, the Miltenyi Biotec team has grown to more than 1,100 employees. They produce and market over 1,400 products for the biomedical research community worldwide,

The RNA probe to the EIA0305 gene was labeled with fluorescein (NEL633) and visualized with NBT (Image courtesy of New England Nuclear) Remember the days when fishing for a sequence in the E. coli genome seemed like an overwhelming task? Somewhere along the way, it see

Nearly 30 years after the discovery of tiny barrel-shape structures called vaults, their natural functions remain elusive. Nevertheless, researchers are beginning to put these nanoparticles to work in biomedicine.
A Look at Drosophila Pattern Formation

Researchers interested in gene expression studies adopt one of two approaches. They can either examine the expression of a given gene in a population of cells in aggregate, or they can study the gene on a cell-by-cell basis in situ. The advantage of the former approach is its simplicity: It is generally easy to prepare RNA or protein from a given tissue sample and to probe it for the gene or protein of interest. But there are several disadvantages associated with the population approach. First o
DNA Chips Enlist in War on Cancer

Graphic: Cathleen Heard The boy had the classic symptoms of acute leukemia--low blood counts and tumor cells circulating in his bloodstream. But the diagnosis was tentative because the tumor cells looked atypical for leukemia. So doctors extracted RNA from the cells, made cDNAs from the RNA, and incubated the cDNAs with a chip bearing thousands of single-stranded gene fragments on its glass surface. The hybridization pattern suggested, surprisingly, that the boy had a muscle tumor. After confirm
