Determine AB0/Rh blood type of real human blood in under five minutes. A small amount of blood is applied to a series of wells containing lyophilized blood typing antibodies, followed by the addition of a wash buffer that flows across each ... 更多

This activity provides the most procedurally accurate simulation of the blood typing technique available. Students test and determine the ABO/Rh blood types of four different simulated blood samples. Using Innovating Sciences' new simulated ... 更多

Blood type, an inherited characteristic, has use in everything from forensic investigations to medical procedures. In this activity, students will learn about the genetics that determine blood type and the possible inheritance patterns and ... 更多

All the food in the world is of no use if the human body does not have the ability to extract necessary nutrients from it. With this activity, students will be able to expose three nutrients (carbohydrates, proteins and lipids) to different ... 更多
