Chromatography in Greek means to ‘write with colors.’ It is a versatile separation technique developed in 1903 by Mikhail Tswett, a Russian botanist. He separated colorful plant pigments using a column of calcium carbonate. Ever since its discovery, chromatography has evolved as a powerful tool in the lab for the separation and identification of different compounds in a mixture.

Drug accumulation alters gut bacterial metabolism and composition

In a research paper recently published in the journal Nature by Klünemann et al. (September 8th, 2021), the interaction of 15 diverse drugs with 25 common strains of gut bacteria is investigated, revealing 70 bacteria-drug interactions that include 29 entirely novel mechanisms not yet reported.

Scientists identify a potent neutralizing nanobody against SARS-CoV-1

In a recently published article in the journal Virologica Sinica, scientists have described the development and validation of a potent nanobody that targets the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus (SARS-CoV). The nanobody efficiently and specifically blocks the interaction between RBD and angiotensin-converting enzyme 2 (ACE2) and neutralizes the virus.
