Mechanism of heparin interference in detection of LIAISON® Rubella IgM.

Aims: To investigate the effects of heparin in detection of LIAISON® Rubella IgM (Rub-M) and the mechanism of interference.

Methods: Different concentrations of lithium heparin and sodium heparin were added to ten serum samples. The relative light units (RLU) value of Rub-M was measured using the LIAISON XL detection system.

GATA-type transcriptional factor Gat1 regulates nitrogen uptake and polymalic acid biosynthesis in polyextremotolerant fungus Aureobasidium pullulans.

Polymalic acid (PMA) is a novel biopolymer produced by the polyextremotolerant fungus Aureobasidium pullulans. In this study, a GATA-family transcriptional factor, Gat1, which regulates nitrogen uptake and PMA biosynthesis, was investigated. PMA production increased to 11.
