Description:
Gelatin is a white or pale yellow, translucent, slightly shiny powder made from the degradation of collagen in connective tissues such as animal skin, bone, muscle membranes and muscle charms. Gelatin has very little solubility in cold water, but can be readily soluble in hot water. Based on this soluble property, gelatin can be used mainly as a sacrificial bio-ink for printing sacrificial materials. It can be washed off when the temperature rises to 37°C.
Note:
The optimal concentration of this bioink depends on the cell type and the research objectives. Dry gelatin can be stored for many years at room temperature in an airtight container. When heated to 100°C in air, it will soften and degrade, releasing pyridine bases and ammonia.
