BioAccord A Quick Look Webcast Series 3:

How we help to ensure the quality of COVID 19 therapeutic antibodies

Immunotherapies use externally derived neutralising antibodies to help patients fight off infection, and this is one strategy being prepared COVID-19.  With faster and cheaper molecule development processes available we are going to see a significant effect from biotechnology on this pandemic.  Immunotherapeutics, being large biologically produced molecules are prone to undesired modifications that can occur from subtle changes in their fermentation, so rigorous analysis batch to batch is necessary.

Here we look at an LC-MS QC strategy that is suitable for product monitoring of immunotherapeutics. The use of the IdeS protease allows rapid profiling of at the subunit domain that can report both large and small post translational modifications that intact mass analysis may not reveal.  To do this we show the application of the BioAccord, UPLC Accurate Mass MS system running the compliant ready UNIFI software for this subunit domain analysis.

Vaccines and glycosylation

Vaccines are one of our exit strategies from COVID-19.  Accelerating vaccine production is a measured risk as it could produce ineffective vaccines or in some cases make infection more severe.

There are many types of vaccine but most rely on presenting a viral glycoprotein to the hosts immune system so it can generate neutralising antibodies.  One way of reducing the risk in vaccine production is to ensure that the glycan profile of that glycoprotein is consistent and relevant to that of the virus. In this video we take a Quick Look at how simplified, compliance ready LC-MS with automated sample prep can provide glycan profiling for the QC environment.

How We Help Ensure that PCR Diagnostics Work for Virus Detection​

Diagnosis of viral infection, including the novel coronavirus relies on accurate PCR tests, which in turn depend on good synthetic oligonucleotide primers.  In this first Quick Look webcast we explore how the quality of these primers is monitored using a simplified, compliant ready accurate mass LC-MS system.
