General description

A high purity, low endotoxin and low IgG BSA powder preparation with near native albumin characteristics. This BSA is first isolated by a proprietary heat-shock/ organic solvent process and further purified by non solvent based methodologies to reduce endotoxins to very low levels resulting in a highly monomeric bovine albumin that retains many of the binding, transfer, and physical properties of native albumin. Purity is = 98%; typical purity is 100%. This BSA may be used for molecular biology applications.

Application

Probumin® BSA products are fit for use as blockers, protein/antibody (conjugate) stabilizers, and in immunoassays (EIA, RIA and serology systems).

Features and Benefits

  • High-quality and reliability. Assurance of consistency in performance and supply.
  • Proprietary heat shock and cold solvent fractionation process optimizes the protein yield, purity, and efficacy of BSA. Large batch capacity.
  • Safe serum sourcing from USDA-licensed facilities exclusively from U.S. cattle.
  • Highly monomeric.
  • Low endotoxin.
  • Low protease.
  • Low fatty acid.
  • Essentially globulin free.
