Transfection Reagent for NCI-H441 Cells (Lung Adenocarcinoma Cells, HTB-174)
- A biodegradable polymer based transfection reagent – once inside the cell, the polymer degrades into smaller less toxic components reducing cell toxicity, facilitating release of the transgene, and improving transfection efficiency
Optimized for intracellular delivery of plasmid DNA, siRNA, microRNA, and mRNA
High transfection efficiency of both siRNA and plasmid DNA without compromising cell viability
Achieve robust siRNA uptake for dependable gene silencing
Effective transfection under conditions of up to 40% serum
Transfection kit includes Transfection Enhancer reagent
Gentle enough to be used for single cell analysis

NCI-H441 Cell Line:
According to a 2014 article in Molecular Pharmaceutics, pharmaceutical inhalation research is limited due to the lack of extensively studied and well characterized in vitro models of human distal lung epithelial phenotype. However, research shows that NCl-H441 cells can potentially serve as a robust model system of human distal lung epithelium. The NCI-H441 cell line was initially established in 1982 by A.F. Gazdar, M. Brower, and D. Carney and associates. The cells were derived from the pericardial fluid from a male patient with papillary adenocarcinoma and can be cloned in soft agar. NCI-H441 cells exhibit an epithelial cellular morphology and express major surfactant apoprotein (SP-A). Also, they have shown to be able to express pulmonary surfactant protein (SP-B). The NCI- H441 cell line has been known to have a doubling time of approximately 58 hours. NCI-H441 cell line is considered an excellent host for a variety of biomedical applications as well as for lung cancer research. Altogen Biosystems offers polymer-based biodegradable transfection reagent kits for the NCI-H441 cell line.
Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into NCI-H441 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 in NCI-H441 cells. DNA plasmid expressing Lamin A or siRNA targeting Lamin A were transfected into NCI-H441 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.
