Thermo Scientific™ Pierce™ Microcentrifuge Tubes, 2.0 mL

These microcentrifuge spin cups and spin columns are convenient tools for manipulating small volumes of affinity supports (5 to 500μL) for immunoprecipitation (IP) and pull-down purification assays. Five styles of polypropylene columns and matching collection tubes offer a variety of options to suit particular types of experimental needs. Add the affinity resin and sample to one of the columns and use a microcentrifuge to efficiently wash away contaminants and elute your purified sample without losing any resin in the process. Spin columns allow you to affinity-purify more protein in less time.

Highlights:

• Efficient washing of samples means fewer washes are needed to remove contaminating proteins
• Efficient elution of samples means better recovery of immunoprecipitation and assay products
• Filter cups and columns eliminate contamination of eluted samples with affinity resin
• Filter cups and columns eliminate the need to decant supernatant from pelleted debris or resin
• Spin protocols drastically reduce the time required for small-scale affinity protocols
• Low protein-binding polypropylene column construction minimizes nonspecific binding
