Promotion of Aggregation as a Means of Assessing the Stability of Antibody Molecules

Thioflavin T aggregation assay to determine antibody stability using the FLUOstar Omega

03-11-2011

The efficiency of antibody molecules is dependent on their stability. We introduce an assay setup where stability of antibodies is measured. Shaking stress is initiated by the FLUOstar Omega microplate reader and aggregation propensity of antibody candidates is measured in 96-well format

Membrane Fluidity Measurements Using UV Fluorescence Polarization and the POLARstar Omega

23-06-2010

The POLARstar Omega microplate reader from BMG LABTECH was used to study membrane fluidity via fluorescence polarization in 96-well format. The method allows for the monitoring of large scale alterations in membrane fluidity (such as phase transitions), as well as more subtle changes in lipid ...

Real-Time Analysis of LNCaP Cell Growth in Different Media

11-01-2010

Our results suggest that the influence of androgen receptor-stimulating or -blocking substances strongly depends upon the composition of the growth medium. The use of hormone-depleted FBS in combination with phenol red-free medium is strongly recommended for monitoring stimulator effects, whereas ...
