Features of Protein Arrays
Proteins are maintained in a non-dried state from production to analysis with Wet Protein Array (WPA) technology.
Using the WPA technology, we can maintain the proteins on the arrays in a non-dried state from production to assay.
This technology allows the analysis of proteins in a state similar to in vivo without denaturing.
Our WPA array analysis service reproduces the immune reactions in vivo at a higher level than any other company.
In vivo Non-dried array (Wet Protein Array technology = WPA)
The amount of antigenic protein is consistent, and there is no missed screening.
The amount of antigenic protein is consistent, and there is no missed screening.
The human antigen proteins on the array are synthesized using the wheat germ cell-free system.
Cell-free systems can synthesize proteins with high efficiency. There is no need to consider the effects of toxicity or expression levels.
84% of all proteins synthesized using our proprietary method are within a 10-fold abundance ratio.
This system is highly consistent, as protein expression systems using live cells have been reported to vary in protein levels by nearly a millionfold.
Our technique can also detect autoantibodies to proteins with low expression levels that are missed by cell-based detection systems.
