Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod

"Lots of companies come out with media or reagents for this or that, and make a big splash, but they're all basically derivatives of traditional products," says Hayden Coon, a former National Institutes of Health re-searcher who is the founder of Human Cell Therapies Inc. of Chebeague Island, Maine. Advanced Biotechnologies Inc. Columbia, MD American Qualex Antibodies La Mirada, CA American Type Culture Collection (ATCC) Rockv

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,

From a rapid molecular test for COVID-19 to tools that can characterize the antibodies produced in the plasma of patients recovering from the disease, this year’s winners reflect the research community’s shared focus in a challenging year.

Date: March 15, 1999 Phage Display Systems and Vectors Structure of the T7 phage particle. The negative-stained pattern from polyheads showing capsid hexamer and pentamer units has been fitted onto the surface of the icosahedral particle. A single monomer of the capsid protein is shaded in red. Figure provided by Novagen. Back in the early '50s, at a time when Elvis Presley was beginning his undisputed reign as the king of rock 'n' roll, bacteriophage were rearing their ugly heads (so to spe

Date: July 5, 1999Table of Cell Signaling Tools At today's research pace, new signaling mechanisms within and between cells are emerging not one by one but in a chain reaction. Each new discovery has strong implications for previously established models, sometimes overturning several assumptions at once. With such a large number of interacting systems--from cell adhesion to differentiation and apoptosis--and receptor pathways, keeping up with the wealth of cell-signaling research tools can be l

Antibody Purification Reagents The immune response is often exploited to produce those remarkably useful affinity reagents known as antibodies. Today's biological and biomedical laboratories employ an array of different immunochemical techniques. For example, a specific antibody can be harnessed to screen for the presence of its respective antigen, quantify the amount of antigen in a given sample, determine the antigen's subcellular location, isolate the antigen from complex mixtures, and sear
