What is pH Meter? A pH meter is a critical instrument used for measuring the acidity or alkalinity of aqueous solutions, quantified in terms of pH. The pH scale ranges from 0 to 14, where a value of 7 denotes neutrality, values below 7 indicate acidity, and values above 7 denote alkalinity. This scale reflects … Read more
What is HPLC (High-performance liquid chromatography)? Principle of HPLC (High-performance liquid chromatography) Instrumentation of HPLC High-Performance Liquid Chromatography (HPLC) is a sophisticated analytical technique that relies on a precise set of instruments to achieve effective separation, detection, and analysis of chemical compounds. The key components of an HPLC system include the mobile phase reservoir, solvent … Read more
Northern blotting or Northern hybridization is a widely used technique in molecular biology to determine the molecular weight of mRNA and to measure relative amounts of mRNA present in different samples and for identifying alternatively spliced transcripts and multigene family members.
