Preparation of Quality Inositol Pyrophosphates

Inositol pyrophosphates play an important role in human pathologies such cancer, diabetes and obesity; however, the exact mechanism of action is a matter of dispute. The lack of commercially available inositol pyrophosphates renders detailed studies problematic. Here we describe a simple protocol to produce and isolate milligrams of inositol...

Phase Transitions: Sublimation and Deposition02:33

Phase Transitions: Sublimation and Deposition

Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

In Vitro Mineralization Assay: A Colorimetric Method to Quantify Osteoblast Calcium Deposits on Bone Graft Substitute by Alizarin Red S Staining and Extraction

In this video, we describe a method for the detection of osteoblast-secreted calcium deposits using an anionic dye, Alizarin Red S. The cultured osteoblasts are first stained and then the dye is recovered for colorimetric quantification of calcium deposits or the degree of osteoblast...
