General description

Donkey serum is pooled from a normal donor herd. In immunoassays, normal donkey serum can serve as a blocking agent and a control. It is used as a blocking agent in various studies for immunohistochemistry and immunocytochemistry, ranging from 5% to 20%.

Application

Donkey serum has been used:
  • as a component in blocking buffer for immunofluorescence
  • in phosphate buffer saline (PBS) as a blocking agent
  • as a blocking agent in frozen immunocytochemistry and immunohistochemistry
  • to prevent nonspecific binding in parvalbumin immunohistochemistry
