Toxoplasma gondii is an important pathogen in the immunocompromised population and in pregnant women. All Toxoplasma gondii products are the RH strain and are produced in mice.
NF1008-DOC strain: RH, in glycine, 0.5% DOC
NF1011 strain: RH, in phosphate buffered saline, 1 mM AEBSF, 10 KIU Aprotinin/ml
NF1012 strain: RH, whole frozen tachyzoites, in phosphate buffered saline
NR1034 strain: RH, formalin fixed whole tachyzoites, in phosphate buffered saline
NF1001 mouse splenic antigen, in phosphate buffered saline
Trypanosoma cruzi is transmitted to humans by the Reduviid bug. Infection causes the host to contract Chagas disease, or American trypanosomiasis, which is an important cause of cardiovascular and gastrointestinal disease in South America. These antigens are a cocktail of three geographically distinct strains.
NF2708 strain: M/HOM/BR/78/SYLVIO-X10 CL1, M/HOM/AR/74/CA-1, and Texas-Tulane, in glycine buffer.
NF2711 strain: M/HOM/BR/78/SYLVIO-X10 CL1, M/HOM/AR/74/CA-1, and Texas-Tulane, in phosphate buffered saline
