When your antibody fails to detect a signal, the problem can be complex. Is it the antibody itself? The sample? Or the protocol? This guide provides a complete troubleshooting protocol for "no signal" Westerns. We dive into the most common reason for failure and then provide a systematic checklist. Learn how to diagnose issues with your transfer using Ponceau S, why your blocking buffer might be the culprit, and how one common preservative could be killing your signal.

Unlock the secrets of the most essential technique in molecular biology! This comprehensive guide to the plasmid miniprep protocol takes you from a single bacterial colony to pure, high-yield DNA. We dive deep into the "3-buffer magic" of alkaline lysis and provide a detailed, step-by-step protocol for both modern silica spin-columns and traditional precipitation methods. Learn to troubleshoot common problems like low yield and gDNA contamination, and get your DNA ready for a

Gibson Assembly and Golden Gate Cloning are two of the most powerful techniques in a molecular biologist's toolbox. While both methods allow for the seamless assembly of multiple DNA fragments, they operate on different principles and are suited for different applications. This article breaks down the pros and cons of each, helping you choose the right cloning strategy for your research. Discover the key differences in their mechanisms, efficiency, and costs to optimize your

Struggling with unexpected bands in your no-template control? PCR contamination is a common yet frustrating hurdle in molecular biology, leading to false positives and unreliable data. This comprehensive guide delves into the root causes of contamination, from ubiquitous product carryover to sneaky environmental DNA. We provide a robust framework for prevention, emphasizing the power of spatial separation, aseptic technique, and decontamination protocols.
