What Is MALDI Imaging Lipidomics

In the realm of modern life sciences and medical research, lipid molecules play pivotal roles as the primary constituents of cell membranes, as well as essential signaling molecules and energy storage entities. However, owing to the vast array of lipid types and their inherently intricate structures, the analysis of lipids presents formidable challenges. Traditional analytical approaches often struggle to unveil the spatial distribution and biological functions of lipid molecules. To gain a profound understanding of the distribution within organisms, metabolic pathways, and their associations with diseases, the MALDI-MSI lipidomics technique has emerged.

Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging (MALDI-MSI) not only facilitates substance identification but also enables spatial distribution imaging of the analyzed entities. In recent years, this technology has been extensively applied in lipidomics research.

MALDI-MSI lipidomics is an analytical approach that integrates the principles of Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging technology with lipidomics, aimed at investigating the spatial distribution and composition of lipid molecules within biological samples.

MALDI-MSI, a mass spectrometry imaging technique, generates molecular distribution maps on the surface of biological samples, thereby providing spatial information about molecules at the tissue and cellular levels. Lipidomics, on the other hand, focuses on studying the types, structures, and relative abundances of lipids within organisms to unveil their roles in biological processes and disease development.

The integration of these two techniques in MALDI-MSI lipidomics allows simultaneous acquisition of spatial distribution and structural information of lipid molecules by performing mass spectrometry imaging in different regions of biological samples. This holds significant value in comprehending the distribution of lipids within cells, tissues, and organs, as well as their roles in physiological and pathological processes. This approach finds crucial applications in biomedical research, drug development, and disease diagnosis, aiding scientists in delving deeper into the relationship between lipids and biological functions.

Our MALDI Imaging Lipidomics Service

Creative Proteomics provides a well-established solution of MALDI-Imaging. Up to a thousand lipid species can be detected, and the result provides both molecular–histological maps from the localization and identification of lipid biomolecules based on mass-to- charge ratio (m/z). Imaging data may be normalized to the total ion current to calculate lipid abundances and subject to statistical test appropriate for the experimental questions. Creative Proteomics provides reliable, rapid and cost-effective lipidomics MALDI-Imaging service to meet your different needs.

Samples That Can Be Analyzed

MALDI-MSI lipidomics proves amenable to an array of biological specimens, encompassing tissue sections, cell cultures, and organism-derived samples.

Analyzable Substances

In the realm of lipid constituents, MALDI-MSI lipidomics emerges as a discerning sentinel, proficient in the discernment and analysis of a diverse array of lipid species. Among its purview are, though not confined to:

Neutral lipids, a cohort exemplified by triglycerides and phospholipids.

Glycolipids, which include the likes of glycosphingolipids and glycerophospholipids.

Cholesterol and its myriad derivatives.

Fatty acids, an assembly encompassing both saturated and unsaturated variants.

Lipid metabolites, such as the gamut of oxidized lipids and lipid peroxides. Further encompassed are lipid-based medicaments and their downstream metabolites.

Notably, MALDI showcases a distinctive prowess in scrutinizing glycerophospholipids (GPL), sphingomyelins (SM), and sulfatides (ST).
