SV40, K661 was isolated from simian immunodeficiency virus (SIV)-infected rhesus monkey brain in 1998.

SV40, K661 is a variant with an archetype-length regulatory region lacking a duplication within the G/C-rich segment and containing a single copy of the 72 base pairs enhancer element in the noncoding regulatory region of the large T antigen of the virus. SV40, K661 is naturally severely attenuated for microRNA expression due to a defect in the processing of the primary microRNA transcript. The complete genome of SV40, K661 has been sequenced (GenBank: AF038616).

Each vial contains approximately 1 mL of clarified cell lysate and supernatant from Cercopithecus aethiops kidney fibroblast cells infected with SV40, K661.
