General description
The targeted highly abundant proteins are simultaneously removed by the immobilized specific IgYs when crude biological samples are passed through the column. Selective immunodepletion provides an enriched pool of low abundance proteins for downstream proteomic analyses. Specific removal of these 14 highly abundant proteins depletes ~95% of the total protein mass from human serum or plasma. The low abundance proteins in the flow-through fractions can then be studied. Removal of highly abundant proteins enables improved resolution and dynamic range for one dimensional electrophoresis (1DGE), two-dimensional (2DGE) electrophoresis and liquid chromatography/ mass spectrometry (LC/MS). The collected flow-through fractions may need to be concentrated dependent upon the downstream application.
Seppro™ IgY14 columns allow users to separate 14 highly abundant proteins (HAP) from plasma protein mixtures. The Avian polyclonal IgY (Immunoglobulin Yolk) antibodies, have a distinct, highly specific partitioning advantage over competing products, allowing the researcher to look at a much cleaner human protein mixture. Seppro™ columns make further proteomics analysis into the plasma proteome much easier and provide cleaner results.

Application
Seppro™ IgY14, LC2 (2 mL bed volume columns) is designed for use as a plasma/serum protein removal tool base upon immune affinity removal of 14 highly abundant proteins (HAP) from human plasma protein mixtures via liquid chromatography. Seppro™ IgY14 is used to support the analysis of low abundance human serum/plasma proteins.
Preparation Note
Store the column at 2–8 °C. After use, equilibrate the column with 1´ Dilution Buffer containing 0.02% sodium azide and store the column at 2–8 °C with the end-caps tightly sealed. Do Not Freeze the column.
Other Notes
If the protein concentration of the sample is unknown and the total serum protein level is potentially elevated, a reduction of the serum load to 24.0 ml is recommended for initial study to avoid potential abundant protein bleed through.
