Additional Information

Storage Conditions

GeBAflex-tube kit must be stored in a dry place at room temperature (15-25°C). Under these conditions, GeBAflex-tube kit can be stored for up to 24 months without any deterioration in performance and quality. For longer storage time, it is recommended that the GeBAflex-tube kit be stored in a cool place (refrigerator), at relative humidity of 35% at least. GeBAflex Tubes with MWCO of 1,000 / 25,000 / 50,000 are delivered wet and must be stored at 4°C.

Product Use Limitations

GeBAflex-tube kit is developed, designed and sold for research purposes only. It is not to be used for human diagnostic purposes or drug production nor for producing any substance intended to be administered to humans unless expressly cleared for that purpose by the Food and Drug Administration in the USA or the appropriate regulatory authorities in the country of use. All due care and attention should be exercised in the handling of materials described in this text.

Quality Control

The performance of GeBAflex-tube kit is regularly monitored. GeBAflex-tube kit is tested by using it for extraction of Proteins, DNA and RNA fragments of various sizes from either agarose or polyacrylamide gel. GeBAflex-tube kit is tested also for simple dialysis of salts or buffer exchange. The quality of the isolated Protein, DNA and RNA fragments or of the sample after dialysis is checked by several assays commonly used for proteins, nucleic acids and dialysis. Determining the recovery from a specific amount of loaded sample tests the quality and efficiency of the GeBAflex-tube membrane.
