Competency Assessment in Clinical Laboratories
Until 1988, there was no administrative need to set up a targeted system for documenting employees’ competency in clinical laboratories. Regular performance evaluations are conducted to evaluate the performance of the clinical laboratory staff for job promotion or increase in salary. Although external proficiency testing assesses the ability to achieve the desired result for a […]
Lab Basics: Centrifuge Rotors, Inserts, and Accessories
Introduction Centrifuges are everyday instruments used in research and clinical laboratories. Different types of rotors, inserts, and accessories are combined with these centrifuges for various applications. Since these rotors and inserts are a significant investment for labs, they must be carefully selected to ensure precise experimental outcomes. Centrifuge rotors can be divided into fixed-angle rotors, […]
Lab Basics: Benchtop Centrifuges
Introduction Benchtop centrifuges are the equipment utilized in laboratories to separate and purify molecular mixtures in a liquid medium based on their density gradient. Centrifugation is a significant practice employed in biochemistry labs for analyzing and isolating cells, subcellular fractions, molecular complexes, and biological macromolecules like proteins, DNA, and RNA. Centrifuges are high-speed devices that […]
sgRNA construction and design
Clustered regularly interspaced short palindromic repeats (CRISPR) technology is a rapid, cheap, and efficient tool to edit genomes at a precise location. CRISPR technology has now been reduced to just two components: Endonuclease and g RNA. Endonuclease makes an incision at the target DNA molecule to be edited, and gRNA is a single-stranded synthetic 20 […]
Centrifuge Rotors: To Choose and to Maintain
As an Amazon Associate, ConductScience Inc. earns revenue from qualifying purchases Introduction Centrifugation is a laboratory technique routinely used to fractionate a given liquid mixture into single components. The basis of the technique is the application of centripetal forces to a sample by spinning it at high velocity. As a consequence, a centrifugal force originates […]
Microtube Homogenizer
Introduction Homogenization is a sophisticated method of achieving substance uniformity by altering and reducing particle sizes. Homogenization methods often include different processes, such as mixing, high-pressure processing, disrupting, emulsifying, dispersing, and stirring of samples (Dhankhar, 2014). Interestingly, the concept of homogenization dates back to 1899 when Auguste Gaulin acquired a patent on his homogenizing machine […]
Made for Spinning: The Centrifuge
Centrifuges – What Are They? Technically, any device that applies centrifugal force to objects by rotating them around a central axis might be called a centrifuge. Centrifuges are devices that apply high-speed spinning to objects, liquid or gas samples, to separate their individual components. Centrifuges contain a rotor where tubes with the samples can be […]
