Indirect ELISA- Rabbit monoclonal [EPR24852-116] to SARS-CoV-2 Spike Glycoprotein S1 - Mouse IgG1 (Chimeric) (ab323455).

Indirect ELISA showing primary antibody ab323455 binding to Recombinant Human coronavirus SARS-CoV-2 Spike Glycoprotein S1 (Fc Chimera, ab272105). Plates were coated with Recombinant Human coronavirus SARS-CoV-2 Spike Glycoprotein S1 (Fc Chimera, ab272105), Recombinant Human coronavirus SARS-CoV-2 Spike Glycoprotein S2 (Fc Chimera, ab272106) and Recombinant human coronavirus SARS spike glycoprotein (Tagged, ab270844) at 1000 ng/ml. Binding of ab323455 was assessed in a serial dilution range 0.016- 1000 ng/mL (a 3-fold serial dilution). Secondary antibody, Goat Anti-Mouse IgG Fc (HRP) preadsorbed (ab98717) was used at 1 : 5000.

This data was developed using the same antibody clone in a different buffer formulation.

Specificity

Our data (not shown) suggests this RabMAb is interacting with the non-receptor binding domain of SARS-CoV-2 Spike Glycoprotein S1 with a higher affinity (~ 71x ) than the receptor binding domain of SARS-CoV-2 Spike Glycoprotein S1.
This antibody cross-reacts with the SARS-CoV-2 Omicron variant spike protein.

Product details

This mouse monoclonal chimeric antibody has been engineered from a RabMAb parent antibody (ab283942). By necessity, some rabbit sequence is retained as part of the variable domain. When multiplexing with other rabbit-derived antibodies, using cross absorbed Fc-reactive secondary antibodies are recommended.

ab323457 is the carrier-free version of ab323455

What are the advantages of a recombinant monoclonal antibody?

Supplementary information

The SARS-CoV-2 Spike Glycoprotein S1 also known as the G10 spike or glycoprotein spike plays an important role in allowing the virus to attach and enter host cells. This protein with a mass of approximately 180 kDa is located on the surface of the virus and forms the outer spikes observed in coronaviruses. Expression of the spike glycoprotein is in virus-infected cells where it facilitates the interaction with host cell receptors. The S1 subunit includes a receptor-binding domain that specifically binds to the human angiotensin-converting enzyme 2 (ACE2) receptors initiating the infection process.
Biological function summary

The spike glycoprotein S1 mediates the fusion of the viral and cellular membranes which is necessary for viral entry. It forms part of a larger trimeric complex comprising S1 and S2 subunits. This complex undergoes conformational changes that drive the membrane fusion process. The glycoprotein contains multiple glycosylation sites which help shield the virus from the host immune response. The proper function and presentation of this glycoprotein are critical for efficient viral spread and infection establishment.

Pathways

The spike glycoprotein S1 is integral to the viral infection pathway and host immune evasion. It interacts with the renin-angiotensin system by binding to the ACE2 receptor disrupting normal receptor activity. This interaction not only facilitates viral entry but also impacts the homeostatic functions typically mediated by ACE2 which include blood pressure regulation. Additionally the spike protein is involved in downstream activation of immune signaling pathways including those related to inflammation and cytokine production which may involve proteins such as IL-6.

Infection with the spike glycoprotein S1 is directly related to COVID-19. The binding to ACE2 receptors is linked to the pathology of the disease contributing to respiratory symptoms and in severe cases acute respiratory distress syndrome (ARDS). Through the IL-6 signaling pathway the spike protein is indirectly connected to cytokine release syndrome often observed in severe COVID-19 cases. This connection highlights the importance of targeting this glycoprotein for potential therapeutic interventions and diagnostics such as ELISA SARS-CoV-2 tests and the development of anti-spike antibodies available on platforms like antispark.com for research and clinical purposes.
