Immunoassays, COVID-19 & Biotech Endeavors

Immunoassays take a shot at the rule of specific antibody to-antigen binding, in which antibodies are utilized to recognize and quantify signatures of microbe contamination.

SARS-CoV-2, the causative agent of COVID-19 (coronavirus 2019), is an individual from the SARS-related types of coronaviruses. This strain is the latest expansion to the rundown of seven known coronaviruses that are pathogenic to homo sapiens. Included here are SARS-CoV and MERS-CoV, which cause the SARS and MERS maladies, individually. Coronaviruses are enveloped RNA infections that cause upper respiratory tract disease in people.

As the COVID-19 pandemic advances, researchers around the globe have been hustling to consider and comprehend everything about SARS-CoV-2, the infection that causes COVID-19.

Immunoassays take a shot at the rule of specific antibody to-antigen binding, in which antibodies are utilized to recognize and quantify signatures of microbe contamination. Infections can be straightforwardly perceived through the focusing of specific viral proteins or antigens. Then again, serum immunoglobulins, (for example, IgG, IgA, and IgM) that an individual has gained as a feature of an immune response can likewise be estimated. These sorts of immunoassays are known as antibody tests. Various immunoassays have gotten endorsement for diagnostic use for COVID-19, using designs like ELISA.


The enzyme-linked immunosorbent assay (ELISA) utilizes enzyme-substrate reactions to deliver quantifiable signs corresponding to the concentration of the target analyte. A characterizing feature of the ELISA is the immobilization of the objective antigen upon a strong surface, as a rule in microplate wells. This can happen by covering the surface with specific antibodies.

 In the event that the target is immunoglobulins, the surface is covered with recombinant proteins. The overall methodology follows in a lot of consecutive steps: sample application and analyte binding, expansion of enzymes conjugated to specific antibodies (typically basic phosphatase or horseradish peroxidase), incubation with the chemical substrate, and recognition on a microplate reader. ELISA kits are delicate, quantitative tests that can be utilized to gauge an assortment of analyte types inside complex samples.

The Need for Biotech Research

Before the COVID-19 pandemic, the focal point of innovation inside the biotech division was slanted towards malignancy, precision medications, and gene therapy. Yet COVID-19 has called attention to that there are more territories that need consideration. The pandemic has reflected the extent of the biotech business, the need to extend zones of examination, and how COVID-19 has not influenced continuous research activities over the globe. In fact, the times of crises induced by corona reflected how much humans are in dire need to expand the scientific research in order to come up with the cure of COVID-19.

A few pieces of research have been published so far that depict some information regarding the lethal coronavirus. One is the Krogan Laboratory’s recent publication ‘A SARS-CoV-2-Human Protein-Protein Interaction Map Reveals Drug Targets and Potential Drug-Repurposing’.

As indicated by Krogan Laboratory’s recent publication, 332 human proteins have been distinguished from communicating with SARS-CoV-2 proteins.

Affinity mass spectrometry (AP-MS) was performed to distinguish associating proteins.

  • Recombinantly expressed coronavirus proteins were transfected into HEK293T cells  
  • SARS-CoV-2 proteins were caught by reactive human proteins
  • Mass spectrometry was run to distinguish the receptive proteins

A few perceptions about the 332 human proteins can be drawn from their findings.  

The distinct interacting proteins are more profoundly communicated in the lungs than in different tissues of the body.

The connection between SARS-CoV-2 and human proteins is related to different biological processes, such as lipid modification, DNA replication, vesicle trafficking, and so on, just as innate immune pathways like the IFN signaling pathway and NF-kB signaling pathway.

These proteins are more developmentally conserved than the normal human protein, which implies the human populace may have comparative versions of these proteins. For the most part, a pandemic-level infection will target profoundly conserved proteins to spread generally inside the human populace.

Out of the 332 human proteins, 67 human proteins or host factors are conceivably druggable.
