Immunoaffinity partitioning of highly-abundant proteins (HAP) has proven to be one of the most effective approaches for overcoming the wide dynamic range of plasma protein concentration, as well as enabling the detection of low-abundant proteins (LAP). Avian polyclonal IgY (Immunoglobulin Yolk) antibodies have unique and advantageous features that allow highly-specific partitioning of protein mixtures. Sigma offers a novel Seppro® IgY-R7 column system, which takes you deeper into the rat plasma/serum proteome.
Rat serum albumin
Seppro® Rat, spin columns (15-20μL capacity) is designed for use as a plasma/serum protein removal tool base upon avian antibody (IgY)-antigen immune affinity removal of seven highly abundant proteins (HAP) from rat plasma protein mixtures via liquid chromatography. Seppro® Rat, spin column is used to support the analysis of low abundance rat serum/plasma proteins.
