illustra™ ProbeQuant™ G-50 micro columns

Supplier: Cytiva

ProbeQuant™ G-50 micro columns use spin column chromatography to provide a fast and reliable method for purifying labelled probes from unincorporated labelled nucleotides. In addition, a portion of the eluted DNA can be counted in a scintillation counter and compared to an unpurified sample to give an approximation of percent incorporation. The columns are designed for use in a microcentrifuge, come prepacked with Sephadex™ G-50 DNA grade and are pre-equilibrated in STE, which means that they are ready to use. They can accommodate samples ranging in volume from 25 μl to 50 μl.

Dye terminator removal, illustra™ AutoSeq™ G-50 columns

Supplier: Cytiva

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.
