COVID-19 Anti-S1, Anti-NC Total Ab

 

COVID-19 Anti-S1/ Anti-NC Total Ab

Serological tests for quantitative and qualitative detection of total antibodies against Spike RBD S1 protein or Nucleocapsid (NC) protein of SARS-CoV-2

IMMUNE RESPONSE ASSESSMENT
by measuring both S1 and NC antibodies.

 

FAST RESULTS
Time to results about 10 minutes.

 

HIGH THROUGHPUT CAPACITY
with full traceability.

 

 

 

BENEFITS OF THE KITS:

  • The quick solution for evaluating immunity status of patients
  • Ideal solution for screening of community and population
  • Applicable on most common clinical chemistry analyzers
  • High performance, ready-to-use reagents, long shelf life and onboard stability
  • Avoid interference due to Biotin and HAMA
  • Better precision and repeatability than rapid card tests
  • Very good correlation with PCR results
  • Environmental sustainable product from ISO 14001:2015 certified company

 

 

THE IDEAL SOLUTION FOR

 

verifying immune response after vaccination

monitoring the spread of infection in population

identifying potential current infections and asymptomatic patients

 

 

Comparison to alternative immunological method:

 

A total of 479 (105 positive and 374 negative) patients samples have been tested with the COVID-19  anti-S1 Total Ab and the COVID-19  anti-NC Total Ab kits and compared to the results of an automated commercial available method for detection of total antibodies to SARS-CoV-2.

Relevant hints from the simultaneous processing of the sample with the two assays:

 

COVID-19 Anti-S1 Total Ab COVID-19 Anti-NC Total Ab Type of antibodies Exposure to the virus
+ + Presence of
– Neutralizing antibodies
– Non-neutralizing antibodies
Possible positivity due to past/present infection
+ Prevalence of
– Neutralizing antibodies
Possible positivity due to vaccination*
+ Prevalence of
– Non-neutralizing antibodies
Possible positivity due to past/present infection**
Absence of antibodies (or not detectable) Possible absence of contact
with the virus

* If absence of Anti-NC antibodies is confirmed
** If  presence of Anti-NC antibodies is confirmed after retesting
