Hydromount is the traditional choice whenever a nonfluorescing aqueous medium is needed. Hydromount is water-based and is suitable for mounting specimens that have been processed in water. Hydromount is effective for frozen sections, amyloid, and immunofluorescent staining procedures. Should it become necessary, Hydromount may be removed by soaking the slides in warm saline.

Stemolecule LDN-193189 in Solution. LDN-193189 is a cell permeable small molecule inhibitor of bone morphogenetic protein (BMP) type I receptors ALK2 and ALK3 (IC50 = 5 nM and 30 nM respectively)1. LDN-193189 was derived from structure-activity relationship studies of Dorsomorphin and functions primarily through prevention of Smad1, Smad5, and Smad8 phosphorylation1-3. LDN-193189 only weakly inhibits ALK4, ALK5, and ALK71. BMP signaling coordinates developmental patterning and has essential physiological roles in mature organisms4,5. LDN-193189 has been used to reduce ectopic ossification in a mouse model of fibrodysplasia ossificans progressiva1.
