General description

Complement serum is prepared from pooled human plasma and lyophilized from the amount of serum indicated on the label.

Application

Complement sera human has been used:
  • to incubate DLD-1 or SW-620 cells to quantify C5a release
  • in multiplex bead antibody-binding assay to assay C3d
  • in complement-dependent cytotoxicity assay
