Collected at government approved abattoirs in the United States
Suitable for use as a serum protein control in immunoelectrophoresis
Sheep red blood cells coated with Rabbit anti-Sheep Cell Hemolysin have traditionally been used to assay the activity of the complement classical pathway in serum samples.
Normal Sheep Serum, 10mL, Physical State: Freeze-dried powder, Protein Concentration: 60mg/mL, Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH: 7.6, Store product at 2 to 8degreeC
Normal serums are lipid extracted to improve clarity, dialyzed against phosphate buffered saline (PBS) containing sodium azide, and freeze dried. Normal serum diluted to 5% (v/v) in PBS is strongly recommended as a blocking reagent to reduce background from non-specific, conserved sequence and/or Fc receptor binding. Best results are obtained with diluted normal serum from the same host as the labeled antibody, as a separate incubation step before addition of the primary antibody.
