The Human IgY14/Supermix LC1 Column

Seppro® Protein Depletion Technology

The Seppro IgY14/Supermix Combo LC1 column contains both IgY14 and Supermix resins with a ratio of 2:1. The resin can be reused up to 100 times.

The Seppro IgY14 resins are based on avian antibody (IgY)-antigen interactions and optimized buffers for sample loading, washing, eluting, and resin regeneration. These IgY14 resins are specifically designed to remove fourteen highly abundant proteins (HAP) from human fluids such as serum or plasma. Our unique SuperMix resin then targets the removal of 50 additional moderately abundant proteins1.

  • The LC1 Sample Capacity is 20 μl based on a protein concentration of 50mg/ml or less
  • Total protein mass removal: 96-99%
  • Targeted HAP depletion efficiency: 95% (average)

The HAP and MAP distributions in the human blood plasma proteome

Figure 1. The HAP and MAP distributions in the human blood plasma proteome. The top 14 HAP are targeted by the IgY14 column (A) and 50 MAP are targeted by the SuperMix column. The percentage of protein abundances are based on spectral count data from LC–MS/MS experiments. In this context, HAP are defined as 14 proteins captured by the IgY14 column, and MAP are those 50 proteins captured by the SuperMix column as listed in Table 1 except C3. All other proteins are considered as LAP.

a The capture efficiency was estimated for each protein based on MS/MS spectral count data by dividing the spectral count for each protein from the bound fraction by the sum of spectral counts from the bound fraction (B) and flow-through fraction (FT), i.e., B/(B + FT). If proteins were not observed in flow-through fraction, these proteins were represented as >99%. IPI00022420.3 Plasma retinol-binding protein.
