Albumin and IgG removal from serum using the
Aurum serum protein mini kit. Serum proteins were electrophoresed before and after treatment with an Aurum serum protein mini column.
Samples (200 µg of protein) were focused on 11 cm ReadyStrip pH 310 IPG strips, then run on Criterion 816% Tris-HCl
precast gels for the second dimension.
Proteomic analysis of serum presents its own unique challenges. Albumin and IgG contribute up to 90%
of the total protein in a serum sample. These proteins obscure
lower-abundance proteins and limit loading capacity on 2-D gels. To obtain meaningful results, these proteins
must be removed prior to downstream separation or analysis.
- Easily and effectively remove albumin, or both albumin and IgG, by affinity chromatography
- Increase sample load of other proteins 3- to 4-fold
- Use a quick and easy spin-column format
- Provide eluted proteins ready for IEF analysis
