The HT-1080 cell line comes from tumorigenic connective tissue originally removed from a 35-year-old male Caucasian patient with fibrosarcoma in 1972. These cells have a susceptibility to an assortment of viruses such as the RD-114 feline virus, polio, vesicular stomatitis virus and feline leukemia virus. These cells are used in research involving connective tissue cancer. Altogen Biosystems facilitates these research studies by manufacturing an HT-1080 transfection reagent for fibrosarcoma cells. The reagent has a high transfection efficacy for siRNA delivery. Transfection Reagent for HT-1080 Cells (Fibrosarcoma Cells, CCL-121)
