Vivaspin 20 50 kDa MWCO PES 12/pk

How to select the right spin column for your application

Sample volume and molecular weight of the target biomolecule(s) are the primary factors to consider when choosing a spin column. Vivaspin offers a choice of membranes to cover different ultrafiltration requirements (Table 1). Tip: For maximum recovery, select a MWCO value at least 50% smaller than the molecular size of the species of interest.

Table 1. Select the appropriate Vivaspin product from the intersection of the molecular weight cutoff value (MWCO value) and the volume range for your sample

Applications for ultrafiltration spin columns

Vivaspin ultrafiltration spin columns are a rapid and flexible solution for protein concentration and small-scale preparation of biological molecules directly from cell lysates and biological fluids, following upstream purification steps. They can also be used prior to downstream analyses, such as gel electrophoresis, liquid chromatography (LC), mass spectrometry (MS), and LC-MS. Examples include:

• Concentration of urine prior to electrophoresis for identification and diagnosis of multiple myeloma and related serum protein disorders.
• Concentration of recombinant human IFN-g following purification from culture supernatant.
