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.

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.
