The A2 has arrived!

Lab Note #11
Jul 29, 2014
After what became a month of extra waiting, the vitamin A2 finally arrived. We promptly verified it and it has been sent to the test subjects.

Starting today, the control resumes taking vitamin A1. Meanwhile our test subjects will be taking 1.6mg of vitamin A2 for the next 25 days. Since the amounts are so small, the A2 (a viscous yellow liquid at room temperature) will be diluted into oil so that a precise measurement can be made. Since it is so susceptible to degradation at room temperature, the A2 is kept in the freezer in aliquots so that only the necessary amount is exposed to room temperature.

The first readings for NIR LED tests will be done this Friday.
