• • Application and Analysis of Advantages of SWATH-MS in Plasma Proteomics

  Plasma is among the most complex and research-relevant biological sample types. It carries protein signatures secreted from tissues throughout the body and is widely used in biomarker discovery, early disease diagnosis, and precision medicine due to its accessibility and high stability. However, plasma proteomics faces two major challenges: 1. An extremely wide dynamic range (>10¹⁰), with a small number of high-abundance proteins (e.g., albumin, globulin) accounting for over 90% of the total protein .......

• • How to Use SWATH-MS for Label-Free Protein Quantification?

  In proteomics research, label-free quantification (LFQ) has become an increasingly prominent approach for differential protein profiling and mechanistic studies. This is largely attributed to its advantages, including the elimination of costly labeling reagents, scalability with respect to sample number, and compatibility with clinical specimens. Among the diverse LFQ strategies, SWATH-MS—representing a data-independent acquisition (DIA)-based method—integrates the broad identification capability of........

• • Yellow Skin: Glycation? MtoZ Biolabs Unravels the Mystery

  Skin - an essential part of our body, not only a marker of external beauty, but also an important reflection of our health status. Glycation is a natural process in the human body that occurs when sugars such as glucose or fructose bind with skin's collagen and elastin proteins, making the skin's collagen stiff, causing the skin to lose its natural structural support, resulting in wrinkles, fine lines, and sagging. Skin glycation is a non-enzymatic biochemical process that involves the reaction betwee......

• • Advanced LC-MS Method for DON (Vomitoxin) Detection in Food Products

  In the domain of food safety, the detection of deoxynivalenol (DON, commonly known as vomitoxin) remains a significant challenge. Produced by specific fungal species, this mycotoxin is frequently detected in grains and flour and can pose a wide range of health risks. With increasing public and industry concern regarding food safety, the accurate detection of DON has become a central focus for both regulatory agencies and food manufacturers. The LC-MS (liquid chromatography–mass spectrometry) platform ......

• • Explore Protein Peptides: MtoZ Biolabs' Solution

  Food protein bioactive peptides are small molecular peptides composed of short-chain amino acids. They not only exist naturally in food but can also be derived from protein degradation in food. These peptides have multiple biological activities, including antioxidant, anti-inflammatory, hypotensive, and immune-regulating properties, making them of significant value in the development of healthy and functional foods.   The Importance of Bioactive Peptides Bioactive peptides are organic, isolated fragme......

• • What Is SWATH Mass Spectrometry?

  With the rapid advancement of proteomics, mass spectrometry has become a central tool for uncovering the molecular mechanisms underlying biological processes. Mass spectrometry techniques have continuously evolved—from early Data-Dependent Acquisition (DDA) methods to more recent Data-Independent Acquisition (DIA) strategies—enabling significant improvements in the depth, accuracy, and reproducibility of proteomic data. Within the DIA framework, SWATH-MS (Sequential Window Acquisition of All Theoretical....
