 New tools for HIV diagnosis: Discover our gp140 portfolio! 

Our solutions to the HIV assay manufacture challenges

The viral entry receptor for HIV-1 and HIV-2 is the Envelope protein gp160, a transmembrane glycoprotein featuring the mature glycoprotein gp120 and the transmembrane protein gp41. Both neutralising and non-neutralising patient antibodies are targeted against gp160, making this protein an exciting diagnostic and vaccine target. gp160 is synthesised as a polyprotein and cleaved by the host-resident protease furin (Checkley et al., 2011).

Removal of the intravirion and transmembrane domains allows for production of a soluble secreted version of gp160 termed gp140. The Native Antigen Company now offers untagged HIV-1 glycoprotein gp140 group M subtypes A, B, C, CRF01-AE, group O, and HIV-2 glycoprotein gp140, enabling a new generation of diagnostic assays and structural studies.

The Role of Serology in Tracking COVID-19 Mutations

This article was originally published on Clinical Lab Products. As SARS-CoV-2 began its global proliferation in early 2020, scientists hastened to investigate its biology, develop diagnostic tests, and design candidate vaccines, marking one of the most...

Preparing for Disease Y: A Better Serological Toolbox

This article was originally published on Clinical Lab Manager. It’s been over a year since the World Health Organization (WHO) declared COVID-19 a pandemic. SARS-CoV-2 has since infected 200 million people, resulting in nearly 4 million deaths and substantial economic...

Keeping Up with the New SARS-CoV-2 Variant Nomenclature

If you’ve been struggling to make sense of SARS-CoV-2 variant nomenclature, you’re not alone. Due to the existence of multiple genomic sequence databases, various naming systems are in use for the rapidly growing range of SARS-CoV-2 variants of concern/interest. In a...

Making Sense of the SARS-CoV-2 Spike Mutations

Through much of 2020, SARS-CoV-2 accumulated mutations at a steady, yet unspectacular rate. However, as global cases approached 100 million by the end of the year, multiple variants began to emerge. Exhibiting more considerable genomic changes, some variants have...

D614G: Putting the Mutation in Perspective

Since the emergence of SARS-CoV-2, scientists have speculated about the risks of mutation and what this could mean for therapeutics and vaccines. In this blog, we explore the nature viral mutation, what is known about the D614G mutant of SARS-CoV-2, and introduce our...

The Endemic Coronaviruses and What They Might Tell us About COVID-19

While less-well known than some of their counterparts, the 229E, NL63, OC43, and HKU1 human coronaviruses are a significant cause of respiratory disease worldwide. The evolutionary histories and host associations of the endemic coronaviruses also provide important...

Q&A: An Insight Into COVID-19 Serology

During the course of the current coronavirus pandemic, we have all been aware of the urgent need for nucleic acid testing to identify people currently infected with SARS-CoV-2. The second form of testing needed are serological immunoassays, which can identify past...
