Cytiva, 28918007, PD MiniTrap™ desalting columns with Sephadex G-25 resin

PD MiniTrap G-25 PD MiniTrap G-25 columns are prepacked, single-use gravity columns for desalting, buffer exchange, and sample cleanup. • Flexible protocols with the ability to use gravity flow or centrifugation. • Convenient desalting and buffer exchange of sample volumes of 0.1 mL to 0.5 mL for gravity and 0.2 mL to 0.5 mL with centrifugation. • Replaces dialysis for desalting protein, which saves time and reduces labor. • Filled with Sephadex G-25 Medium resin. Column for desalting and buffer exchange of proteins PD MiniTrap G-25 is designed for convenient desalting of biological samples. For increased flexibility, the protein desalting column can be used with either gravity or centrifugation. When using the gravity protocol, clean-up of the sample is simple. One or several columns can be connected in parallel, and a purification system is not needed. With the centrifugation protocol, the samples are run in parallel in a standard centrifuge.The eluted sample will have minimal dilution. Four adapters are included in each product pack. The adapters simplify centrifugation of these protein desalting columns. The exclusion limit is approximately M r 5000. This ensures group separation of proteins/peptides larger than M r 5000 from smaller molecules. Successful use in published research PD MiniTrap G-25 are used in a variety of research applications, including: Buffer exchange during in vitro assembly of catalase Removal of DTT during study of thiosulfate transfer in Metallosphaera cuprina Imidazole removal during study of disparate ligand binding sites in the human P2Y1 receptor Other Cytiva products for buffer exchange or desalting PD SpinTrap G-25 spin column for small sample quantities using a benchtop centrifuge – up to 180 µL sample volume PD MidiTrap G-25 gravity column for sample volumes up to 1 mL PD-10 Desalting gravity column for sample volumes up to 2.5 mL HiTrap Desalting columns for sample volumes up to 1.5 mL. For use with a syringe, a peristaltic pump, or a chromatography system HiPrep Desalting column for sample volumes up to 15 mL. For use with a laboratory pump or a chromatography system PD MultiTrap G-25 for high-throughput desalting and buffer exchange of multiple samples This resin is available as bulk resin
