描述: A pre-mixed dye solution used in cell culture applications to determine cell viability. A researcher can remove a sample of cells from culture and combine in a 1:1 ratio with the Trypan Blue solution. Under the microscope, dead cells will appear a blue color and viable cells will appear clear and translucent. Using a hemacytometer (gridded microscope slide), a researcher can quantify the percentage of dead cells within a population. Stained cells are ready for counting within five minutes.

描述: illustra™ AutoSeq™ G-50 columns are specifically designed to remove fluorescent dye-terminators from sequencing reactions prior to analysis on automated sequencers. Effective purification is essential for high quality sequencing results since residual dye-terminators can obscure data. illustra™ AutoSeq™ G-50 consists of MicroSpin™ columns containing Sephadex™ G-50, pre-equilibrated in double-distilled water. This is important because even the small amount of salt in traditional buffers (such as TE buffer) can cause electrophoretic artifacts on salt-sensitive automated sequencers.
