Delivery impact due to the Coronavirus Outbreak

With the COVID-19 outbreak in the world, many flights have been cancelled. In order for the customer to receive the goods properly, we use the FedEx Customized Freight (FCF) of Fedex which demands a higher fee. If the delivery fee is more expensive in your area, we will contact you by mail.

Spike mutant variant of SARS-COV-2 (2019nCOV) B.1.1.7 lineage spreaded in UK

The world is in midst of the COVID-19 pandemic. Recently a novel SARS-COV-2 (2019nCOV) lineage, the B.1.1.7 lineage, with serials of site mutation, shows stronger infection ability in the UK. The SARS-COV-2 B.1.1.7 lineage carries a larger than a usual number of coronavirus genetic changes.

The Spike protein (S-protein) of SARS-CoV-2 (2019nCoV) mediates receptor (ACE2) binding and cell entry and is the dominant target of the immune system.

In SARS-COV-2 B.1.1.7 lineage, most mutations and deletions occur in the coronavirus spike protein. These include spike position 501, one of the key contact residues in the receptor-binding domain (RBD), and experimental data suggest mutation N501Y can increase ACE2 receptor affinity (Starr et al. 2020) and P681H, one of 4 residues comprising the insertion that creates a furin cleavage site between S1 and S2 in spike. The S1/S2 furin cleavage site of SARS-CoV-2 is not found in closely related coronaviruses and has been shown to promote entry into respiratory epithelial cells and transmission in animal models (Hoffmann, Kleine-Weber, and Pöhlmann 2020; Peacock et al. 2020; Zhu et al. 2020). N501Y has been associated with increased infectivity and virulence in a mouse model (Gu et al. 2020). Both N501Y and P681H have been observed independently but not to our knowledge in combination before now.

Also present is the deletion of two amino acids at sites 69-70 in spike - this mutation is one of a number of recurrent deletions observed in the N terminal domain of Spike (McCarthy et al. 2020; Kemp et al. 2020) and has been seen in multiple lineages linked to several RBD mutations. For example, it arose in the mink-associated outbreak in Denmark on the background of the Y453F RBD mutation, and in humans in association with the N439K RBD mutation, accounting for its relatively high frequency in the global genome data (~3000 sequences).

GeneMedi pseudotype virus (pseudovirus) of SARS-COV-2 (2019nCOV) B.1.1.7 lineage

Taking responsibility to help accelerate the COVID-19 vaccine and therapeutic antibody discovery and development, GeneMedi had developed the pseudotype virus (pseudovirus) of SARS-COV-2 (2019nCOV) B.1.1.7 lineage, which will meet the evaluation of the efficacy of COVID19 vaccines and therapeutic antibodies.
