| Hazard Information | Back Directory | [Description]
Maltotetraose is a tetrasaccharide that is composed of glucose molecules linked by α-1,4 glycosidic bonds and has been found in B. stearothermophilus.1,2,3,4 It increases the α-amylase synthesis rate in B. stearothermophilus 3-fold greater than sucrose or glucose (Item No. 23733) when used at a concentration of 0.1 mM.2 Maltotetraose (750 μg/ml) inhibits the growth of E. carotovora in a cylinder-agar plate assay but does not affect the growth of several other microorganisms.4 It also inhibits TNF-α-induced expression of intercellular adhesion molecule-1 (ICAM-1) in MOVAS-1 mouse smooth muscle cells (VSMCs) transfected with an ICAM-1 luciferase reporter when used at a concentration of 20 μM.5 | [Chemical Properties]
