Capturem Streptavidin
Capturem Streptavidin miniprep is a single-use disposable column for simple, rapid enrichment of target proteins and antibodies that bind biotinylated proteins. The membranes are guaranteed to bind more than 15 μg of biotinylated BSA control per column. These miniprep columns are suitable for enrichment of target proteins and antibodies, including those from animal serum, cell culture lysates (e.g., mammalian or bacterial cell lysates), and cell culture supernatants of hybridoma cell lines.
Overview
- Simple, ultra-fast workflow: 5–15-minute room-temperature protocols
- High concentration: extremely small elution volumes yield highly concentrated complexes
- High quality: short residence times reduce the possibility of aggregation, complex dissociation, or loss of activity
- High reproducibility: consistent results from well to well
- Single use: novel membrane technology assembled into disposable spin columns reduces the risk of contamination and carryover
Applications
- Purification or enrichment of biotinylated proteins
- Pull-down of binding partners (e.g., proteins or oligos) for a biotin-labeled ligand
Antibody enrichment performed on Capturem Streptavidin mini spin columns
Successive capture of antibodies in triplicate using Capturem Streptavidin. Panels A–C. First, 48 µg of biotinylated rabbit IgG in 200 µl Binding Buffer was passed through an equilibrated Capturem Streptavidin spin column, and 32.0 ± 1.4 µg (Panel B) was successfully immobilized on the membrane. Following a single wash step, a sample containing the spiked-in target antibody (~100 µg of anti-rabbit IgG from goat) in hybridoma medium with 20% mouse serum was diluted with Binding Buffer and applied to the Capturem Streptavidin column. After two successive washing steps with Binding Buffer and then PBS, the enriched target antibody was eluted from the biotinylated capture antibody in 1.0 M glycine in three steps to yield 42 ± 5 µg (Panel C) of highly pure target antibody.
Capturem Protein A- or G-functionalized membranes
Antibody purification workflow for Capturem Protein A or G 96-well plates. Each well can be loaded with up to 850 µl of a diluted sample (antibody sample diluted from 1:1 to 1:20 with buffer). Following binding, the membrane is then washed and the bound antibiody eluted with the appropriate buffers. Note: Protocol time varies for each format. Check user manuals for specifics on protocol times.
Capturem spin columns and filtration devices
Available Capturem spin column and filtration device formats. Pictured from left to right: nanoprep, miniprep, 96-well, 24-well, maxiprep, and large-volume Capturem formats. Formats available vary for the different functionalized membranes. Check product pages for list of available formats.
