• 1. Cell Transfection

  Cell transfection은 관심있는 외부 gene을 세포에 인공적으로 도입하여 외부 DNA가 세포 내에서 발현되도록 하는 과정입니다. 이를 통해 세포의 특성을 변화시켜 유전자나 단백질의 발현과 기능을 연구할 수 있습니다. 다양한 화학적, 물리적, 바이러스 매개 방법이 사용되며, 특히 HEK-293T 세포는 transfection 효율이 높아 널리 사용됩니다. 또한 epitope tagging 기술을 통해 단백질의 특성을 분석할 수 있습니다.

• 2. Cell Lysis

  Cell lysis는 세포막이 파괴되어 세포 내용물이 분산 또는 용해되는 현상을 말합니다. Western blot 등의 실험에서 특정 단백질을 분석하기 위해 세포를 lysis하여 단백질 혼합물을 얻습니다. lysis buffer는 단백질 변성을 방지하고 안정성을 유지하기 위해 다양한 성분으로 구성됩니다. 실험 목적과 단백질 특성에 따라 적절한 lysis buffer를 선택해야 합니다.

• 1. Cell Transfection

  Cell transfection is a critical technique in molecular biology and biotechnology, allowing researchers to introduce foreign genetic material into cells. This process enables the study of gene function, protein expression, and cellular pathways, as well as the development of therapeutic applications. The successful transfection of cells depends on various factors, including the choice of transfection method, the properties of the genetic material being introduced, and the characteristics of the target cells. Effective cell transfection can lead to valuable insights into cellular processes and the development of innovative treatments for a wide range of diseases. However, it is essential to carefully optimize the transfection protocol and consider potential off-target effects or unintended consequences. Overall, cell transfection remains a powerful tool for advancing our understanding of cellular biology and driving progress in the field of biomedical research.

• 2. Cell Lysis

  Cell lysis is a fundamental technique in molecular biology and biochemistry, enabling the extraction and analysis of cellular contents, such as proteins, nucleic acids, and other biomolecules. This process involves the disruption of the cell membrane and the release of the cell's internal components, which can then be studied or used for various applications. The choice of cell lysis method depends on the specific cell type, the target analytes, and the downstream analysis or applications. Effective cell lysis is crucial for a wide range of research and diagnostic applications, including protein purification, gene expression analysis, and the development of therapeutic agents. However, it is essential to carefully optimize the lysis protocol to ensure the preservation of the integrity and functionality of the target biomolecules. Additionally, the potential for contamination or degradation of the cellular contents must be considered. Overall, cell lysis remains a fundamental technique that enables the exploration of cellular processes and the advancement of scientific knowledge and technological applications.
