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).

More COVID-19 research on mucosal immune system required, scientists say
Researchers have said that more COVID-19 studies should focus on the mucous membranes of the nose and mouth, to reveal insights into SARS-CoV-2 immunity.

Antibodies from previous COVID-19 infection protect patients for six months
A study in healthcare workers has shown that antibodies from COVID-19 infection protect individuals from reinfection for at least six months.
news
Antibody effector functions are key to combatting COVID-19, finds study
Rodent studies show that using antibodies with different targets and modes of action in combination is more effective at preventing and treating COVID-19.

£4 million in funding announced to collect data on COVID-19 antibodies
UKRI will provide £4 million in funding to establish a data infrastructure for scientists in the UK to study antibodies from COVID-19 patient samples.
news
Potential strategy to treat COVID-19-related cytokine storms identified
Researchers have found that neutralising antibodies for the TNF-alpha and IFN-gamma cytokines can prevent death from SARS-CoV-2 in mice.

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.

Anti-C5aR antibody shows promise as immuno-oncology treatment
Pre-clinical studies have shown that the TJ210/MOR210 monoclonal antibody is successful at targeting tumours.

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).
news
Pre-existing coronavirus antibodies could protect against new COVID-19 strains
Researchers have found antibodies, from infection with common cold coronaviruses, can also target SARS-CoV-2 - especially in children.
news
Children produce a different antibody response to SARS-CoV-2 infection, finds study
A new analysis reveals that the course of SARS-CoV-2 infection and the immune response it provokes is completely different in adults and children.
news
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.
