Application note: Accurate measurements on the Octet platform without added sample purification steps
Bioanalytical systems have rapidly developed over the past 10 years for lead selection during cell-line development. The advanced technologies for the timely and cost-effective screening of antibodies or vaccines involve consideration of quantitation, kinetics and other critical quality attributes (CQA).

Development of a physiologically relevant lung model for understanding SARS-CoV-2 infection
COVID-19 is known to infect the lungs; however, the dynamics of viral infection and replication are poorly understood. Alongside the Liverpool School of Tropical Medicine, Professor Lyle Armstrong and colleagues have been working to develop a human lung epithelium model of SARS-CoV-2 infection and replication. In this article, he describes…

Developing nanobodies and sybodies to combat COVID-19
Three separate studies have identified nanobodies – a miniature form of antibodies found in camelid species – that can bind to the SARS-CoV-2 Spike (S) protein and neutralise the virus in cells.

Novel antibody-drug candidate to treat pancreatic cancer developed
Scientists have developed a new antibody-drug conjugate (ADC), made from ICAM1, an antibody that targets pancreatic cancer and the cytotoxic drug DM1 (mertansine).

T cells facilitate chronic lung injury in the elderly after viral infections, finds study
After viral pneumonia in elderly mice, there is an accumulation of dysfunctional tissue-resident memory T cells in the lungs which scientists suggest may drive chronic inflammation and fibrosis.

Midbrain organoids developed for automated chemical screening
Researchers have used small molecule neural precursor cells to develop midbrain organoids that enable drug effects to be assessed in a complex cell environment.

Autoantibodies and over-active neutrophils may be cause of COVID-19 blood clots
According to a new study, blood clots in patients with severe COVID-19 are caused by an autoimmune antibody that circulates in the blood and attacks cells.
