MtoZ Biolabs offers Sweat Quantitative Proteomic Solutions, a high-resolution LC-MS/MS based service for in-depth protein identification and accurate quantification from sweat samples. Our Sweat Quantitative Proteomic Solutions support clinical proteomics, biomarker discovery, and translational research focused on systemic physiology, exercise biology, and metabolic or inflammatory conditions.
Introduction
Sweat contains a complex mixture of proteins, peptides, electrolytes, metabolites, and trace biomarkers derived from sweat glands, skin surface, and the systemic circulation. Unlike blood collection, sweat sampling can often be performed repeatedly and under dynamic conditions such as exercise, thermal stress, or drug challenge, making it highly attractive for longitudinal monitoring.
The sweat proteome reflects multiple biological processes, including:
-
Glandular secretion and ductal transport
-
Electrolyte and fluid homeostasis
-
Local skin immunity and barrier function
-
Systemic inflammatory and metabolic status
Quantitative sweat proteomics allows researchers to track protein abundance changes associated with dehydration, heat adaptation, exercise performance, metabolic syndrome, cardiovascular risk, cystic fibrosis, and other systemic or dermatological conditions. By combining controlled sampling strategies with high-sensitivity mass spectrometry, sweat quantitative proteomics can help identify candidate biomarkers, support non-invasive monitoring, and complement blood or urine based assays.
Sweat Quantitative Proteomic Solutions at MtoZ Biolabs
MtoZ Biolabs provides Sweat Quantitative Proteomic Solutions on an integrated LC-MS/MS platform tailored to low-volume, low-abundance sweat samples. Based on DIA technology, MtoZ Biolabs offers both discovery proteomics and targeted proteomics for sweat analysis.
Discovery proteomics delivers deep, unbiased profiling across thousands of proteins to map global expression patterns, identify candidate biomarkers, and compare conditions or subject groups.
Targeted proteomics focuses on predefined protein panels, enabling high-precision quantification of key markers such as inflammatory mediators, stress-response proteins, and skin barrier related proteins for verification and longitudinal monitoring.
This design supports both exploratory biomarker discovery and focused verification within the same technical framework. You only need to submit your samples, and MtoZ Biolabs manages extraction, digestion, LC-MS acquisition, data processing, and biological interpretation.

FAQ
Q1: What types of samples are suitable?
-
Sweat collected using absorbent patches or strips
-
Sweat collected into microvials or capillary tubes
-
Cells related to sweat gland or skin models
-
Purified proteins extracted from sweat or sweat-related samples
Q2: How should I prepare my samples?
1. Use standardized collection devices and record body site and condition (rest, exercise, heat, etc.)
2. Avoid creams, lotions, or topical products on the sampling area before collection
3. Transfer sweat to low-binding tubes if needed and snap-freeze as soon as possible
4. Do not add detergents, high salts, or strong reducing agents that interfere with LC-MS/MS
5. Store samples at -80 °C and ship on dry ice
