How would set up a serial dilution to cover a concentration range from approximately 21 µM to 120 µM of DHF in anassay (in the well) having a total volume of 200 µL of which 30 µL is DHF solution? You are provided a 800 µM DHFstock solution. You need to make a set of DHF dilutions in Eppendorf tubes first.   From these you will take 30 µL eachand dilute into total volume of 200 µL in the wells

can you plase give me the ansewer step by step please

Explain why first electron affinities for neutral atoms tend to increase going across a period (i.e., from left to right) and up a group (i.e., bottom to top) in the Periodic Table.

what is the mechanism to get ornithine from glutamate-5-semialdehyde

How do metal salts affect catalase activity? Why are some metal salts considered to be activators and others are considered to be inhibitors? How do you know if a metal salt is an activator or inhibitor? For example, between K, Mg, Zn, Ca, and Fe, which metal salt would be the activator and which would be the inhibitor? How do you know?
