This research project is looking for the following:

We would be interested in comparing the monoclonal antibodies we isolate, with those obtained by other groups

Abstract or additional information (if available)*

We have assembled a team of molecular virologists, immunologists and frontline infection and critical-care clinicians from King’s College London and Guy’s & St Thomas’ Hospitals; using carefully curated sets of consecutive specimens collected from local patients and staff under the appropriate ethical framework, we will: 1) Characterise the quality and nature of antibody responses to SARS-CoV-2, taking into account both clinical history and prior exposures to seasonal (non-fatal) coronaviruses; 2) Map at the molecular/atomic level the viral components that are targeted by protective (neutralising) antibodies and block SARS-CoV-2 infection; 3) Molecularly clone and characterise the immunoglobulin genes for antibodies with potent neutralising behaviour to understand the features required for protection - such antibodies represent potential COVID-19 immunotherapeutics; and 4) Depending on timing and the state of the epidemic, leverage the detailed knowledge of beneficial antibody attributes for donor screening for convalescent serum therapy in intensive care patients
