Gel purification of DNA is a common technique used for the isolation of specific DNA fragments. However, most methods either fail to completely remove agarose (which can lead to problems in downstream manipulations), shear the DNA, or result in very low yields.

Supplier: CYTIVA PALL

Low extractable, binder-free borosilicate glass fibre filters. Suitable for use of the EPA 1311 Toxicity Characteristics Leaching Procedure and for prefiltration of dirty HPLC samples.

The GSH/GSSG-Glo™ Assay is a luminescence-based system for the detection and quantification of total glutathione (GSH +GSSG), GSSG and GSH/GSSG ratios in cultured cells. A change in GSH levels is important in the assessment of toxicological responses and is an indicator of oxidative stress, potentially leading to apoptosis or cell death. The assay provides a simple, rapid multiwell-plate format where stable luminescent signals are correlated with either the total GSH or the GSSG concentration of a sample directly in culture wells.

QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. The test strips are intended for single use, maintenance or calibration are not required.
