COS-7 Cell Line:
COS-7 was established from a CV-1 line derived from kidney cells of the African green monkey (Cercopithecus aethiops) through transformation with a mutant version of the SV-40 genome that can produce large T antigen. They are fibroblast-like cells growing as monolayers. The COS-7 cell line is frequently used by researchers to study the SV-40 monkey virus. It is also used to transfect cells to produce recombinant proteins for biochemistry, molecular and cellular biology experiments. COS-7 has been shown to retain complete permissiveness for lytic growth of SV40, support the replication of tsA209 virus at 40°C, and support the replication of pure populations of SV40 mutants.
Figure 1. siRNA targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into Cos-7 cells following the recommended protocol. At 48 hours post-transfection the cells were analyzed by qRT-PCR for gene expression levels. 18S rRNA levels were used to normalize the Lamin A/C data. Values are normalized to untreated sample. Data are means ± SD (n=3).
Figure 2. Protein expression of Lamin A/C in Cos-7 cells. DNA plasmid expressing Lamin A/C or siRNA targeting Lamin A/C were transfected into Cos-7 cells following Altogen Biosystems transfection protocol. At 72 hours post-transfection the cells were analyzed by Western Blot for protein expression levels (normalized by total protein, 10 µg of total protein loaded per each well). Untreated cells used as a negative control.
