Know More About Covid Antibody Test
Structural Proteins of SARS-CoV-2
- Four structural proteins of SARS-CoV-2:
- Envelope(E)-formsviralenvelope
- Membrane(M) – forms viral envelope
- Nucleocapsid(N)- binds to viral RNA genome
- Spike(S)- binds to human receptors
- These proteins form the viral capsid, that compact the viral genome
- They help the virus to replicate, protect it from degradation and promote its entry into the host



- At least 10 variants of the COVID virus identified
- Their impact on spread and mortality is still under research
- Nomenclature of these variants by WHO:
- It is confusing to know the efficacy of a vaccine against any one viral variant
- Many vaccine brands are sold across the globe; namely-
- Alpha
- Beta
- Gamma
- Delta
- Epsilon
- Zeta
- Eta
- Theta
- Iota
- Kappa
- Covaxin
- Covishield
- Sputnik
- Pfizer
- Moderna
- Sinovac
- CanSinoBlO
- AstraZeneca
- Johnson & Johnson
COVID Antibodies to Measure Vaccine Impact
- Alpha
- Beta
- Gamma
- Delta
- Epsilon

There is also a different class of binding antibodies called Neutralizing antibodies. Ideally, when virus gains entry into the body, to cause infection it binds to the receptor (ACE-2) on the lung cell with the help of Receptor Binding Domain (RBD) on the viral spike protein. This entry is blocked by Neutralizing antibodies.

We understand that every information about COVID is confusing. Therefore, after performing over 10,00,000 investigations and
experimenting with all the leading brands & technologies for the past 10 months, we have launched this package, with a hope to help
you understand the presence of antibodies and learn which package is ideal for you.
With options from single antibody to combination at affordable costs-we aim to fulfill the needs of all the segments of clients.
We are sure that just like our Aarogyam Packages, these Cantibodies packages too will be used and appreciated.
