Product Information

Activity NK cells activated with this product have a cytotoxic index (T-C) of at least 15%
Formulation Lyophilized
Stability & Storage Samples are stable for up to 24 months from date of receipt at 4 ℃.
Recommend to aliquot OK432 into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.



OK432 is a freeze-dried devitalized bacterium. OK432-activated neutrophils could kill IFN-γor TNF-α treated cancers cell. OK432 could induce neutrophil-killing effect on autologous tumor cells through CD11b/CD18 and ICAM-1 binding. OK432-induced monocytes are able to kill autologous tumor cells. After stimulation by OK432, lymphocytes show fine LAK Cell activity and can even fight against anti-NK tumor cells.
