Only prolidase I activity is present in human plasma.

1. After ion exchange chromatographic separation, liver prolidase exhibits two isoforms (prolidase I and II). 2.

The culture of human skin fibroblasts on microcarriers in the presence of serum substitute: Ultroser G.

The effects of the substitution of serum by Ultroser G on human skin fibroblasts cultured on microcarriers were analysed. Cultures could not be established on microcarriers in the presence of Ultroser G. However, microcarrier cultures started in the presence of 10% foetal calf serum, and transferred to 2% Ultroser G after 7 days resulted in high cell densities.

Activity of the two prolidase isoforms in rat liver after chronic CCl4 intoxication.

The two isoforms of rat liver prolidase were separated by ion exchange chromatography. Both isoforms were similarly increased on fibrosis-inducing CCl4 intoxication in rat.

Prolinase activity in prolidase-deficient fibroblasts.

The activity of prolinase (EC 3.4.13.
