Bacteria Harbor Geometric “Organelles”
Amber Dance | Dec 1, 2018 | 10+ min read
Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.
Monoclonal Antibodies Find Utility In Cell Biology
Ricki Lewis | Dec 11, 1994 | 10+ min read
But, just as antibodies are finding increasing utility in cell biology, a new Food and Drug Administration classification for those products with clinical utility may affect researchers' access to the important technology (see accompanying story). Monoclonal History MAbs were born in 1975, when Georges Kohler and Cesar Milstein at the Medical Research Council Laboratories in Cambridge, England, fused two types of cells to form a hy
