In Vivo Monitoring of Intracellular Expression of Human interleukin-2 Using Green Fluorescent Protein Fusion Partner in Pichia Pastoris

Hyung Joon Cha et al. Biotechnol Lett.

Abstract

The use of Pichia pastoris for protein production was simplified by creation of fusion proteins containing green fluorescent protein (GFP) and the product of interest. Human interleukin-2 (hIL-2) was used as a model product: GFP enabled clear identification of fusion protein expression and, more importantly, the quantification of hIL-2. Although GFP fusions for bioprocess monitoring have been demonstrated in other hosts, this is its first use in P. pastoris.
