    Species: Human
    Sample type: Plasma, CSF (Inflammation in the brain during covid)
We tested three plasma samples from vaccinated individuals as well as 6 donors or unkown vaccination status. The assay worked beautifully and we were able to confirm whether the plasma samples had measurable levels of anti-Spike protein IgG. Easy to use kit and great results.

Great Kit. I used it to screen mice sera for IgG against CoV-2 Spike protein. I was advised to use anti-Mouse-IgG-Biotin instead of anti-Human-IgG-Biotin. It worked very well. Definitely I recommends this kit.

Our laboratory was contracted to perform antibody testing for COVID19. We don't have the time or experience to develop an ELIZA method from scratch. By using and validating these kits. We were able to add a new service to our offerings within days. Using these kits, we were able to get repeatability and linearity between 3 different kits made on different days.
