What Should Flow Through HPLC Column?
What Should You Flow, and What Shouldn’t in HPLC? It Depends on Your Column! What you flow, what you avoid flowing, and in what order, all depend on your column’s stationary phase and physical parameters. Let’s break it down scientifically: Stationary Phase Chemistry 1. Reversed-phase columns (like C18): 2. Normal-phase ... Read More
Troubleshooting in HPLC | A Detective Game in the Lab
Even the best HPLC methods sometimes run into trouble. Poor peak shapes? pressure spikes? incorrect retention times? You need to identify define the problem, define which component(s) may be causing it, then solve it. This process is called troubleshooting. It’s an art as much as it is a science. Think ...

Glomerulonephritis (GN)
Glomerulonephritis (GN) is a group of kidney diseases that involve inflammation of the glomeruli, which are the filtering units of the kidneys. Here are some key points about GN: Types of Glomerulonephritis: 1. Acute glomerulonephritis: Sudden onset of inflammation and damage to the glomeruli. 2. Chronic glomerulonephritis: Long-term inflammation and ... Read More

Why Protein Folding Matters?
Proteins are tiny machines that must fold into the right shape to work. Imagine folding a piece of paper into a paper airplane. If the folds are done right, you get a perfect flying airplane. One wrong fold? It doesn’t fly—it falls apart. That’s exactly how proteins behave. Why Is ... Read More
DNA Extraction Process
DNA extraction is more than just a lab technique; it’s a process rooted in biochemistry and molecular biology principles. 1. DNA extraction A process of isolating DNA from cells or tissues to study its structure, sequence, or function. This process involves breaking open cells, separating DNA from other cellular components, ... Read More
What Makes a Protein Functional?
Proteins are not just strings of amino acids they are complex, highly structured, dynamic molecule that must fold correctly to function properly. But what exactly determines whether a protein is functional? Here are some factors that determine proteins functionality: Primary Structure Protein Folding Post-Translational Modifications (PTMs) Molecular Interactions Environmental factors ... Read More
Conducting BE Studies for NTI Drugs
Here’s a detailed explanation of how bioequivalence (BE) studies are conducted for narrow therapeutic index (NTI) drugs, including regulatory expectations, study design, analytical methods, and statistical analysis: Detailed Overview: Bioequivalence Study for NTI Drugs What are NTI Drugs? NTI (Narrow Therapeutic Index) drugs are those where small differences in dose ... Read More
DCP vs. MRP | Choosing the Right Regulatory Pathway in the EU
Navigating the European regulatory landscape can be complex, especially when seeking approval for medicinal products across multiple countries. Two key procedures streamline this process: Decentralized Procedure (DCP) and Mutual Recognition Procedure (MRP). While both facilitate multi-country approvals, understanding their differences is essential for strategic regulatory planning. Decentralized Procedure (DCP) DCP ... Read More
Handling Conflicting Regulatory Requirements | A Strategic Approach
In global regulatory affairs, one of the most complex challenges we face is resolving conflicting requirements from different regulatory bodies. Each agency has its own set of expectations, shaped by regional regulations, scientific perspectives, and risk tolerance. Navigating these differences requires a strategic, risk-based approach to ensure compliance while maintaining ... Read More
