OBJECTIVE The objective of this lab was to determine the effects of two unknown drugs on the microtubule pathways in COS-7 cells through the process of immunostaining. METHOD Before arrival‚ the COS-7 cells were grown in culture dishes submerged in a growth medium that contained bovine serum. Two coverslips covered in the COS-7 cells were provided. After washing the coverslip with Phosphate Buffer Saline (PBS)‚ one coverslip was treated with the control solution‚ and the other was treated with

This experiment tested the growth of E.coli with inserted plasmid on an agar plate with Ampicillin. One colony of E.coli resistant to Ampicillin was grown during this experiment. The overall goal of the experiment was to successfully grow E.coli on the agar plate‚ which would show that the plasmid had been effectively inserted into the bacteria’s genes. This experiment helped students understand how plasmids were inserted into bacteria and used in real life situations. It also showed how the bacteria’s
