Fluorouracil (5-FU) is an anticancer agent widely used in laboratory research for its ability to inhibit DNA and RNA synthesis in cancer cells. Available in 5g quantities, this reagent is commonly used to study cell growth, gene expression, and cancer cell biology. 5-FU works by interfering with the synthesis of nucleotides, which are essential for DNA and RNA production. Its ability to inhibit cell division makes it useful for cancer research, particularly in studying tumor biology, cell cycle regulation, and drug resistance. The 5g quantity is ideal for smaller-scale experiments, allowing for efficient handling and use in oncology-related research.
