Answer:The recommended sample volume is approximately 30–130 µL.
Answer:The column can remove salts, excess dyes, biotin and other low-molecular-weight compounds from larger biomolecules.
Answer:This configuration contains 25 individual columns.
Zeba™ Spin Desalting Columns, 7K MWCO, 0.5 mL are designed for fast protein desalting and buffer exchange using a centrifuge-based size-exclusion workflow. The proprietary resin has a 7 kDa molecular-weight cutoff and is intended for sample volumes of approximately 30–130 µL. During centrifugation, proteins and other larger biomolecules pass through the column while salts, unreacted fluorescent labels, biotin and other small contaminants are separated by the resin. The method supports applications such as mass spectrometry sample preparation, HPLC, capillary electrophoresis and general assay development. This package contains 25 ready-to-use 0.5 mL spin columns. The smaller pack size is useful when the same Zeba chemistry is required for lower-throughput laboratories, method development or occasional desalting without purchasing the 50-column configuration.
