Lab essentials with Emily

This week Rachel was out of town, so with the help of another graduate student and the South Farm ranch hands, I assisted with bleeding eight calves for tests.  We did the same measurements as last week and we pulled two samples of blood per calf and spun the samples for testing on the blood serum and plasma.  We used pipettes to transfer the serum and plasma into tubes and placed them in the freezer for further testing.  The samples were divided into eight tubes per calf: four for plasma and four for serum.  I learned how to spin down blood and was able to separate the plasma and serum from the other components of the blood samples.  We also labeled more tubes for next week when we bleed four more calves for the study.
