Blood Products:

Whole Blood, Serum & Plasma

+ Optimized for use as positive and negative controls and for evaluating matrix effects and spike recovery assessments

+ Low temperature processing techniques are used to ensure high complement activity while maintaining low cytotoxicity when used in compliment fixation tests


+ Prepared from healthy, non-medicated animals using very large pools to minimize lot-to-lot variability

+ Often used in conjunction with Sheep RBCs and Anti-Sheep RBC products

Red Blood Cells

+ Aseptically collected and prepared-to-order from our on-site vivarium

+ Our anti-RBC antibodies are also available for sequesterng and agglutinating red blood cells, preventing interference in your assay
