BT-20 Cell Line:

BT-20 was established in 1958 by isolation and culturing of cells which were derived from a human breast carcinoma tumor. These cells came from a 74-year-old Caucasian female patient who suffered from breast cancer. This cell line was established by E.Y. Lasfargues and L. Ozzello. A growth factors are often used when studying these cells. BT-20 cells don’t possess estrogen receptors, but do express an estrogen receptor mRNA that has deletion of exon 5. This cell line is useful for biomedical research related to breast cancer, which affects many people every year.


BT20 Transfection Reagent

Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into BT20 cells following the recommended protocol. At 48 hours post-transfection the cells were analyzed by qRT-PCR for Lamin A/C 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=4).


Figure 2. Protein expression of Lamin A/C in BT-20 cells. DNA plasmid expressing Lamin A/C or siRNA targeting Lamin A/C were transfected into BT-20 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.

Altogen Biosystems:

Altogen Biosystems provides preoptimized transfection products for life science research applications. Transfection protocols are optimized for individual cancer cell lines. Altogen Biosystems developed two types of in vivo delivery kits for animal research: Tissue-targeted reagents (delivery to liver, pancreas, and kidney tissues), and broad range in vivo delivery reagents (PEG-Liposome, Nanoparticle-based, Lipid-based, and Polymer-based kits). Advanced formulation of reagents and optimized transfection protocols provide efficient intracellular delivery of proteins, DNA, RNA, and any other negatively charged molecules in vitro and in vivo.
