During the summer, several hens have been busy laying eggs to provide us with yolk with anti-SARS-CoV-2 polyclonal antibodies. And we are excited about the good results of the quality analysis – highly specific and premium purity of antibodies.
The preparation of the Ovodan Biotech IgY undergoes two steps of purification:
Step 1: Purification of the total immunoglobulin fraction from the egg yolk.
Step 2: Affinity purification with the specific antigen used for immunization. This step results in a purity of minimum 95% antigen specific antibody and is non-comparable with the total immunoglobulin fraction.
As avian antibodies, IgY, does not recognize staphylococcal protein A and streptococcal protein G you will avoid cross reactions with these molecules likely to be found in nasal swaps or saliva samples.
This makes the Ovodan Biotech COVID-19 antibodies a perfect reagent for the COVID-19 antigen quick test or bulk test. And we agree – we still need to speed up response time and lower the expenses.
Are you ready to test the Ovodan Biotech COVID-19 antibodies in your POC-assay?
