In order to assess the quality of EVAg viruses and viral products, a set of inscription criteria for EVAg products has been reviewed and developed.
EVAg Virus products
5 categories of virus products :

Category 1 represents the highest quality standards of EVAg viruses. It contains all the viruses that meet the following criteria:
Freeze dried
complete coding sequence or complete genomic sequence
mycoplasmae free
infectivity quantified (ID50 or pfu)

Category 2 viruses are:
Frozen
complete coding sequence or complete genomic sequence
mycoplasma free
infectivity quantified (ID50 or pfu)

Category 3 viruses contains all viruses that meet the following criteria:
Freeze dried
complete coding sequence or complete genomic sequence
mycoplama tested (whatever the result)
infectivity tested (not quantified)

Category 4 gathers viruses that are:
Frozen
Complete coding sequence or complete genomic sequence
Mycoplama tested
Infectivity tested

Category 5 viruses represents <25% of strains entered into the EVAg catalogue (Portal). They are viruses that have incomplete but significant molecular characterisation (Partial sequence) or viruses for which the test for mycoplasmic content was not performed.

EVAg cloned nucleic acids
4 categories of cloned nucleic acids :

Category 1 represents the cloned nucleic acids that meet the following criteria:
cDNA fully sequenced and controlled
No mutation compared to reference sequence

Category 2 cloned nucleic acids have:
cDNA fully sequenced and controlled
Mutations mentioned (no frameshift, no unexpected STOP codon accepted)

Category 3 contains all nucleic acids that meet the following criteria:
cDNA partly sequenced and controlled
no mutation compared to reference sequence

Category 4 gathers cloned nucleic acids that have:
cDNA partly sequenced and controlled
Mutations mentioned (no frameshift, no unexpected STOP codon accepted)

EVAg antibodies
5 categories of antibodies :

Category 1 represents the highest quality standards of EVAg antibodies. Antibodies in this category are:
Monoclonal
Purified by affinity
Specificity documented
Characterised by at least 3 out of the 5 following methods : Western Blot, ELISA, IFA, neutralisation, immunoprecipitation

Category 2 antibodies are:
Monoclonal
Purified by affinity
Specificity documented
Characterised by at least 1 out of the 5 following methods : Western Blot, ELISA, IFA, neutralisation, immunoprecipitation

Category 3 contains all antibodies that meet the following criteria:
Monoclonal
Purified by affinity
Specificity not documented
Characterised by at least 1 out of the 5 following methods : Western Blot, ELISA, IFA, neutralisation, immunoprecipitation

Category 4 gathers antibodies that are:
Polyclonal
Purified by affinity

Category 5 corresponds to sera, and unpurified polyclonal or monoclonal antibodies.

EVAg proteins
4 categories of proteins:

Category 1 proteins meet the following criteria:
Purified (> 95%)
functionally characterised (enzymatic or antigenic)
Mass Spec characterisation for the sample product

Category 2 proteins are:
Purified (> 95%)
functionally characterised (enzymatic or antigenic)
But NO Mass Spec characterisation for the sample product

Category 3 contains all proteins that meet the following criteria:
Purified (> 95%)
NO functional characterisation

Category 4 proteins are the unpurified proteins or partly purified proteins (expression host lysate, presence of the protein assessed by immunoassay)
