The development of bioprocesses requires careful monitoring of numerous parameters such as cell density, viability and product titer. Developing sophisticated feeding strategies is challenging due to the high number of required experiments. Especially if multi single-use systems (e.g. shake flasks) are used, the analysis of the time course of titers leads to a highnumber of samples.

This further increases the time for process development. PAIA antibody quantification assays are a fast and easy way to determine titers in very small sample volumes allowing for multiple sampling even in small bioreactor formats.
