Biotechnology within current medicine has been serving a very crucial role and changing the aspect of diagnosis, treatment, and prevention of diseases. One such large application is the field of new drug and therapy developments. This technique allows development of biologics, as they are called, like monoclonal antibodies to target specific components of diseases, such as cancer.
Another huge application of biotechnology in medicine is genetic engineering. For instance, CRISPR-Cas9 technologies, which enable the specific editing of DNA, promise to effect cures for disorders with a genetic basis, such as cystic fibrosis and sickle cell anemia. This technology further contributes to the development of gene therapy by making possible the replacement of defective genes with normal ones.
Biotechnology also gives new dimensions to diagnostics. Using polymerase chain reaction (PCR) including next-generation sequencing, advanced molecular diagnostic technologies have been developed for the early and accurate identification of diseases at a genetic level. This forms a basis that supports the paradigm of personalized medicine using precision in treatment by basing its actions on the individual genetic constitution.
Additionally, the production of vaccines against COVID-19 using biotechnology uses mRNA to develop immunity without subjecting the individual to the live form of the virus. This has hastened the development and rollout of such vaccines and has been the best demonstration of how biotechnology translates into public health.

High-Performance Liquid Chromatography (HPLC) is an analytical technique used to separate, identify, and quantify components in a mixture. It works by passing a liquid sample through a column packed with a stationary phase under high pressure. The sample components interact differently with the stationary phase, causing them to elute at different times. Detection is then performed, often using UV-Vis spectroscopy, to analyze the separated components based on their retention times. HPLC is widely used in pharmaceuticals, environmental testing, and biochemical research for its high resolution and sensitivity.

The Bacterial Endotoxin Test (BET) is a crucial standard practice for quality assurance in the biopharmaceutical industry due to its role in ensuring the safety and efficacy of pharmaceutical products. Endotoxins, also known as lipopolysaccharides (LPS), are toxic components of the outer membrane of Gram-negative bacteria. When introduced into the human body, even in minute quantities, endotoxins can trigger severe immune responses, including fever, inflammation, and potentially life-threatening septic shock. Therefore, it is imperative to detect and quantify endotoxins in biopharmaceutical products, especially those administered parenterally.
The BET is mandated by regulatory agencies such as the FDA and EMA to ensure that products meet stringent safety standards. This test uses Limulus Amebocyte Lysate (LAL), derived from horseshoe crab blood, which reacts specifically with endotoxins, forming a gel clot or triggering a colorimetric or turbidimetric response. The sensitivity and specificity of the BET make it an essential tool for detecting endotoxin contamination at very low levels.
Implementing BET helps in maintaining product safety, protecting patient health, and ensuring regulatory compliance. It is a critical component of the quality control process, safeguarding against endotoxin-induced adverse reactions and enhancing the overall reliability of biopharmaceutical products.

Gel Electrophoresis
Gel electrophoresis is a method by which DNA fragments or other macromolecules (RNA, proteins, etc.,) are dissociated according to their varying size and charge. DNA samples are loaded into small indentations known as ‘wells’ which are arranged along the extreme side of the gel. The gel molded like a slab, is made from a polysaccharide called ‘agarose’ and is highly porous in nature.
When electric current is passed along this apparatus, the DNA will move towards the positive electrode in virtue of its negative charge. Small fragments of DNA move swiftly compared to the larger ones. After the partition the DNA fragments can be visualized as bands of different sizes by utilizing DNA binding dyes an UV light.
This method has widespread practical applications in Polymerase Chain Reaction, DNA Finger Printing, detection of specific gene sets and species identification in molecular levels.
