  Cell Cryopreservation Cryopreservation, also known as cryogenic preservation, is a process where biological cells, tissues, and organs are preserved at very low temperatures for long periods of time. The ultra-low temperatures slow biological activity, essentially stopping it almost or even completely. This allows cell samples, tissues, or whole organs to be stored indefinitely for future use in research, therapies, and clinical applications. Cells and tissues can then be "thawed" back to normal temperatures when needed for future use. Techniques There are several techniques used for cell cryopreservation, with the most common being freezing cells with cryoprotective agents at ultra-low temperatures, usually around -80°C to -196°C with liquid nitrogen. The main stages of typical cryopreservation protocols involve adding a cryoprotective agent to cells prior to cooling, cooling cells in a controlled manner to ultra-low temperatures, then storing them in ultra-low tempera...

  Red Biotechnology New Frontiers in Gene and Red Biotechnology Scientific advancements in genetics and molecular biology have opened new possibilities for treating various diseases using gene and cell therapy approaches. By delivering therapeutic genes directly into patients' cells or replacing dysfunctional cells with healthy ones, these therapies aim to correct underlying genetic defects. Several clinical trials over the past decade have demonstrated success in treating rare genetic disorders, certain types of cancer, and metabolic conditions. Looking ahead, researchers are working to expand these therapies to more common diseases like heart disease, diabetes, and neurodegenerative disorders. Gene therapies may also help develop vaccines against infectious illnesses and regenerate damaged tissues. If safety and efficacy hurdles are overcome, gene and cell therapies could revolutionize medicine in the coming years. Growing Focus on Personalized Medicine Another key area in Re...

  Next Generation Sequencing The Dawn of a New Era in DNA Sequencing Since the completion of the Human Genome Project in 2003, DNA sequencing has revolutionized our understanding of human genetics and disease. However, the laboratory techniques used in the project, such as Sanger sequencing, were expensive and labor-intensive, generating sequencing data at a relatively slow pace. This all changed with the advent of next-generation sequencing (NGS) technologies in 2005. NGS employs various high-throughput platforms that allow scientists to sequence DNA and RNA much more rapidly than previous methods. Massively Parallel Sequencing   One of the key innovations of NGS is its ability to sequence millions of DNA fragments simultaneously. This is achieved through methods such as sequencing-by-synthesis, in which DNA fragments are amplified on a solid surface and fluorescently labeled nucleotides are added one at a time while a camera captures the incorporation in real time.
