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.

Reactive black 5 ≥50 % (dye content), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Reactive Black 5 (RB5) has been: used in an optimization study on the photocatalytic degradation of RB5 dye in synthetic greywater effluent (i.e. aqueous RB5 in distilled water), in order to understand the effects of different photoreactor parameters on the degradation kinetics. As a textile dye to investigate the anaerobic reduction in upflow stirred packed-bed reactors (USPBRs) with biological activated carbon (BAC) system. Used in the performance evaluation of dye removal forlarge molecule substance.

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.
