Table of Contents Polymerase Chain Reaction is one of the most widely used molecular biology techniques for DNA analysis, diagnostics and research. However, there are times when even professionals encounter situations where the PCR is not amplifying DNA as expected. A failed reaction may delay experiments, increase costs, and affect the reliability of the results.

HEPA filters are one of the most crucial components of any biosafety cabinet, it ensures that harmful airborne particles are trapped before they can contaminate samples, expose laboratory personnel, or escape into the environment. Even though these filters are set to achieve an efficiency of 99.97% for particles as small as 0.3 microns, they are
Why HEPA Filters Fail in Biosafety Cabinets? Read More »
A biosafety cabinet is a ventilated enclosure used in laboratories and designed to protect laboratory personnel, research samples, and the surrounding environment from biological contamination. The best equipment for labs depends on the type of research, biosafety level, airflow requirements, and the category of cabinet. Laboratories working with infectious agents, cell cultures, pharmaceuticals, and microbiological

Laminar air flow systems typically use HEPA filters with an efficiency of 99.97% at 0.3 microns. This implies that the filter can remove about 99.97% of airborne particles that are 0.3 micrometers, which is considered the most penetrating particle size. Laminar air flow systems are an integral part of laboratories, manufacturing units of pharmaceutical companies,

Electrophoresis is one of the basic techniques in molecular biology laboratories used to separate DNA, RNA, and proteins based on size and charge. While gels, buffers, and chambers receive maximum attention, power supply is that component that directly controls accuracy, reproducibility, and safety. Read this guide to understand the significance of power supply for electrophoresis

Gel electrophoresis results in the separation of DNA, RNA, and proteins based on different principles. DNA and RNA separation takes place based on size by using agarose or polyacrylamide gels. On the other hand, protein separation occurs based on size and charge using SDS-PAGE or native PAGE. Each method uses specific buffers, stains, and conditions
