HEK Cells
HEK Cells (Human Embryonic Kidney cells) are widely used laboratory tools in biotechnology and pharmaceutical research. Think of them as reliable, well-understood test subjects for studying how drugs work, producing proteins, and testing new medical treatments. Scientists like using HEK cells because they're easy to grow, adapt well to lab conditions, and reliably produce results. They're similar to other lab-grown cells like CHO cells or HeLa cells. These cells serve as a standard testing platform in drug development and biological research, making them a common requirement in biotech job descriptions.
