Trypan Blue Cell Counting

Monitoring and analyzing cell culture with state-of-the-art solutions. Reliable and efficient monitoring is crucial for optimizing yield and product quality since even small changes in bioprocess parameters can influence the performance of your cell culture. Cell count and viability are the most important parameters, Countstar® Altair supplies an extremely smart and fully comply with cGMP solution for these.

During the bioprocess, GFP is often used to fuse with recombinant protein as an indicator. Determine the GFP fluorescent can reflect the target protein expression. Countstar Rigel offers a fast and simple assay for testing GFP transfection as well as viability. Cells were stained with Propidium iodide (PI) and Hoechst 33342 to define the dead cell population and total cell population. Countstar Rigel offers a quick, quantitative method for evaluating GFP expression efficiency and viability at the same time.
