Our unique Wuxian Express custom protein production platform for generation of R&D-grade proteins and antibodies is designed to fill the gap between transient production and traditional stable pool methodologies. Compared to transient production, Wuxian Express delivers significantly more material, yet only adds 1 week to the overall timeline. Compared to the traditional stable pool production, Wuxian Express is 6 weeks faster and thus offers significant time and cost savings to obtain the same production scale.
