Product Description:

Optimized transfection kit for high transfection efficiency of 3T3-L1 cell line originating from mouse embryonic fibroblasts, these cells have the remarkable ability to differentiate into adipocytes under appropriate culture conditions.Used in biological and medical research, particularly in the study of adipocyte differentiation, metabolism, and obesity-related diseases.

3T3 Cell Line:

The 3T3-L1 cell line was established in 1974 from a Swiss albino mouse (Mus musculus) embryo. This cell line exhibits fibroblast morphology and is very similar to the 3T3 cell line, from which it is derived. These cells do not carry ectromelia virus (mousepox). 3T3-L1 could be useful for studying fibroblast cells, or mammalian embryonic tissue. This cell line has been known to double nearly every 14 hours. 3T3-L1 cells are sensitive to lipolytic and lipogenic hormones and drugs such as epinephrine, isoproterenol, and insulin. Progressing from a rapidly dividing to a confluent and contact inhibited state, 3T3-L1 cell line undergoes a pre-adipose to adipose-like conversion. 3T3-L1 is an embryonic mouse fibroblast cell line widely used in the study of adipose tissue as its cells can differentiate into adipocytes under proper conditions. Altogen Biosystems provides lipid-based transfection kits for the 3T3-L1 cell line.

3T3L1 is a mouse embryonic fibroblast cell line that is commonly used as a model for studying adipocyte differentiation and metabolism. These cells were originally isolated in 1962 from Swiss mouse embryo tissue and have since been widely used in research. 3T3L1 cells can be induced to differentiate into adipocytes, which makes them useful for investigating the molecular mechanisms involved in adipogenesis. Adipogenesis is the process by which preadipocytes differentiate into mature adipocytes, which are the primary cell type responsible for storing and releasing energy in the form of triglycerides. During adipocyte differentiation, 3T3L1 cells undergo a series of morphological and biochemical changes, including the upregulation of adipogenic transcription factors such as PPARγ and C/EBPα, the accumulation of lipid droplets, and the expression of adipocyte-specific genes such as adiponectin and leptin. 3T3L1 cells have been used in a wide range of research applications, including the investigation of the molecular mechanisms underlying obesity and metabolic disorders, the identification of novel anti-obesity agents, and the development of adipose tissue engineering strategies. Additionally, 3T3L1 cells have been used to study the effects of various environmental factors, such as diet and exercise, on adipocyte metabolism and function.

3T3L1 Transfection Reagent

Figure 1. siRNAs targeting Lamin A/C mRNA or non-silencing control siRNA were transfected into 3T3L1 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 3T3-L1 cells. DNA plasmid expressing Lamin A/C or siRNA targeting Lamin A/C were transfected into 3T3-L1 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.
