3) Corroboration of results using a commercial kit ELISA based
on the spike RBD antigen s
This finding of the presence of SARS COV-2 like antibodies in Camels in
Kenya based on our crude lysate ELISA, was corroborated by the results
obtained using the commercial kit based on the Spike specific RBD
antigen (Figure 9 & 10). One potential explanation for the generally
higher OD scores in crude lysate ELISA relative to the commercial kit is
that the crude lysate ELISA could include up to 4 (NP, S1 & S2 and M)
major antigens as opposed to the single antigen (Spike RBD) in the
commercial kit.
