IgY Rat-Specific Columns

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.

Proteins Partitioned by IgY-R7 columns: 

  • Rat serum albumin
  • IgG
  • Fibrinogen
  • Transferrin
  • IgM
  • Haptoglobin
  • alpha1-Antitrypsin

Columns are available in the following formats:
