Transfection Reagent for AGS Cells (Gastric Adenocarcinoma, CRL1739)
- A biodegradable polymer based trasfection agent – 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
- Download AGS CRISPR/Cas9 transfection protocol: [PDF]
- Download PowerPoint presentation for AGS cells transfection kit: [PPT]
- Developed and manufactured by Altogen Biosystems
Reagent exhibits at least 77% transfection efficiency of siRNA delivery. Transfection efficiency was determined by real-time RT-PCR.

AGS Cell Line:
Gastric cancer remains difficult to cure and is considered the third primary cause of death from cancer worldwide. Because of the lack of early symptoms, it is hard to detect and is often diagnosed at an advanced stage. Inhibition of histone deacetylase (HDAC) was found to suppress the growth of gastric adenocarcinoma cells, as per the 2015 study published in the International Journal of Oncology. siRNA transfection was one of the research methods utilized to explore the progress of HDAC regulation in the cancer cells. The AGS gastric adenocarcinoma cell line is extensively employed in preclinical studies of stomach cancer. The AGS cell line was initially established in 1979 from the stomach tissue of a 54-year-old Caucasian female who suffered from gastric adenocarcinoma (stomach cancer). These cells exhibit epithelial cell morphology and are tumorigenic. The patient received no prior therapy before removal of these cells. AGS cells could be used for research related to different forms of stomach cancer. Altogen Biosystems provides a highly sensitive polymer-based transfection reagent kit for the AGS stomach cancer cell line.
Figure 1. GAPD mRNA levels were quantified using real-time RT-PCR in the AGS cells transfected with siRNAs targeting GAPD or non-silencing siRNA. Forty-eight hours post-transfection, the cells were harvested and analyzed by real-time RT-PCR for GAPD mRNA expression levels. Data were normalized against the 18S rRNA signal. Control samples were either mock-transfected or untreated. Values are normalized to untreated sample. Data are means ± SD (n=5).
Figure 2. Protein expression of GAPDH in AGS cells. DNA plasmid expressing GAPDH or siRNA targeting GAPDH were transfected into AGS 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.
