Transfection Reagent for Caco-2 Cells (Colon Adenocarcinoma Cell, HTB-37)
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, si/shRNA, 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
- Gentle enough to be used for single cell analysis

Caco-2 Cell Line:
The earlier colon cancer is diagnosed, the better the outlook for complete recovery and survival. However, despite the recent cancer breakthroughs, it can be extremely challenging to increase life expectancy in patients with late-stage colon cancer. The Caco-2 cell line is established from a patient with colorectal carcinoma and is widely known for its rapid differentiating ability. With a modal chromosome number of 96, many of these cells are polyploidy. The Caco-2 cell line is susceptible to human immunodeficiency virus 1 and could be potentially useful for the study of certain types of colon cancer in humans. This cell line has been known to double every ~62 hours. Transfection is a powerful investigative research tool that can be used to study molecular and biochemical pathways in cancer cells. Altogen Biosystems provides efficient biodegradable transfection reagent kits for the Caco-2 colon cancer cell line. A polymer-based transfection Caco-2 kit for colon adenocarcinoma cells yields at least 94% transfection efficiency and is a helpful tool for gene expression studies as well as for assessing cellular functionality.
Figure 1. GAPD mRNA levels were quantified using real-time qPCR in the Caco-2 cells transfected with siRNAs targeting GAPD or non-silencing siRNA. Forty-eight hours post-transfection, the cells were harvested and analyzed by real-time qPCR 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 Caco-2 cells. DNA plasmid expressing GAPDH or siRNA targeting GAPDH were transfected into Caco-2 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.
