3D-MPLA-3A is a research-grade 3-O-deacylated-4'-monophosphoryl lipid A (3-DMPLA) in the 3-acylated form, derived from the lipopolysaccharide (LPS) of Salmonella minnesota Re595. This product is specifically intended for immunological and molecular biology studies focused on TLR4 signaling, structure-activity relationship (SAR) analysis, and the comparative evaluation of lipid A analogs. The 3A tri-acyl carbon chain structure makes this variant especially valuable in studies where reduced immune activation is desired. Compared with the more potent 6-acyl (6A) form, 3D-MPLA-3A demonstrates minimal activity in human immune cells and has been investigated for potential antagonistic behavior. This makes it an important research tool for scientists exploring receptor modulation, inflammatory pathway control, and the development of novel therapeutic strategies for autoimmune and allergic disease applications. As a research-use product, 3D-MPLA-3A is suitable for laboratories working in immunology, cell signaling, innate immunity, and drug discovery. It is particularly relevant for projects examining how structural differences in monophosphoryl lipid A influence TLR4 receptor response, biological potency, and downstream immune activation. Its defined source, precise molecular form, and research-grade quality make it a strong choice for reproducible experimental workflows and advanced immunological screening. For B2B buyers, this product is positioned as a specialized research reagent rather than a general-use biochemical, making it ideal for universities, biotech companies, pharmaceutical R&D teams, and contract research organizations seeking a specific lipid A analog for targeted studies.
