Maresins Analysis Service

Maresins are a new class of anti-inflammatory and pro-lipid mediators biosynthesized from docosahexaenoic acid (DHA) by macrophages. It has a conjugated double bond system and shows strong anti-inflammatory and solubilizing activities. Maresins limit the further recruitment of PMN, inhibit the infiltration of neutrophils in the body, and stimulate the non-inflammatory recruitment of monocytes.

When macrophages encounter maresins, they increase phagocytosis and efferocytosis, resulting in the removal of microbes. Biosynthesized maresins counterregulate the proinflammatory cytokines such as IL-1β, IL-6, and TNF-α. They also regulate nuclear factor kappa B (NF-κB) gene products and increase the regulation of T cell de novo synthesis and intracellular levels of cyclic adenosine monophosphate, regenerate tissue, and play a role in antinociceptive action.

Creative Proteomics provides comprehensive maresins analysis services from lipid extraction, lipid detection and data analysis for biomedical research institutions, biotechnology and pharmaceutical companies.

Our Maresins Analysis Service

Absolute quantification: Use external standard method to quantify, and use internal standard for correction, qualitative and quantitative is more accurate.

High sensitivity: We use liquid chromatography coupled with triple quadrupole mass spectrometers for maresins analysis service (Triple Quad™ 6500 LC-MS/MS System).
