Quantifying antibody-mediated neutralization of SARS-CoV-2 directly in serum

The emergence of mutant variants of SARS-CoV-2 and associated concerns about the effects of these mutations on the efficacy of vaccines and therapeutics has underscored the vital importance of understanding the antibody response to SARS-CoV-2.In our recent paper "In vitro measurements of protein–protein interactions show that antibody affinity governs the inhibition of SARS-CoV-2 spike/ACE2 binding in convalescent serum" we showcase the unique capabilities of our Fluidity One-W Serum platform and describe:

•

A new type of in-solution receptor-binding competition assay that quantifies the affinity, concentration, and neutralization potential of antibodies against the SARS-CoV-2 spike protein

•

The ability of this platform to accurately and quantitatively profile the underlying protein interactions directly in serum

If you have any questions about our technology or would like to see how the unique capabilities of the Fluidity One-W Serum can support your research, please get in touch and we will be happy to discuss your projects with you.

Logix Smart™ Coronavirus 2019 (COVID-19) Test Kit

The Logix Smart™ Coronavirus Disease 2019 (COVID-19) Test kit is an in vitro diagnostic test that uses our patented CoPrimer™ technology for the qualitative detection of the RNA from SARS-CoV-2 coronavirus (COVID-19).

Ready-to-use Master Mix, complete with RNaseP internal positive control to verify sample quality
Positive Control (PC), to verify the performance of the master mix
Nuclease-Free Water as a negative control, to verify master mix is free from contamination

Intended Use

SARS-CoV-2 is the virus that causes COVID-19, a contagious, zoonotic disease that causes respiratory infection varying from common cold symptoms to severe pneumonia and occasionally death.The Logix Smart Coronavirus Disease 2019 (COVID-19) test is a real-time RT-PCR test using a proprietary technology called CoPrimers™ (Satterfield, 2014)(Poritz & Ririe, 2014) intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in lower respiratory tract fluids (e.g. bronchoalveolar lavage, sputum, tracheal aspirate), and upper respiratory tract fluids (e.g. nasopharyngeal and oropharyngeal swabs) from individuals with signs and symptoms of infection who are suspected of having COVID-19. The test is available to laboratories certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA), 42 U.S.C. §263a, to perform high complexity tests, or by similarly qualified non-U.S. laboratories.Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information.The Logix Smart Coronavirus Disease 2019 (COVID-19) is intended for use by trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures. The Logix Smart Coronavirus Disease 2019 (COVID-19) test is only for use under the Food and Drug Administration’s Emergency Use Authorization.

Why Single-Cell Westerns?

Many cell populations, such as tumor cells or differentiating stem cells, are heterogeneous. Protein expression measurements made at the population level often overlook significant differences in expression between individual cells and the existence of cell subpopulations. Milo combines single-cell resolution with the power and versatility of Westerns. This approach allows simultaneous measurement of multiple proteins in over 1,000 single cells using commercially available Western-validated antibodies.

Milo lets you:

Identify cell subpopulations you can’t see with conventional Westerns
Resolve protein isoforms in individual cells
Identify target expression heterogeneity
Count and quantitate at the same time

Explore how Milo can help you!
