*Begin growing <i>E. Coli</i> for ADA expression. The ADA made [[User:Michael_F._Nagle/Notebook/Chem_571/2012/11/28|will be used to nucleate AuNPs]] | |||
*make elution and binding buffers to be used for extraction and purification of ADA | |||
*prepare solutions of tris in Au/BSA, to be analyzed by UV/Vis to determine how various concentrations affect AuNPs in solution | |||
==Procedure== | |||
*Expressing ADA | |||
** Cultures were prepared and <i>E. Coli</i> with a plasmid for Adenosine Deaminase (ADA) were added and incubated overnight, by [[User:Mary_Mendoza/Notebook/CHEM_571_Experimental_Biological_Chemistry_I/2012/09/19|Mary Mendoza]]. She also prepared binding and elution buffers for extraction. | |||
**Binding and elution buffers were prepared by [[User:Puja_Mody/Notebook/Chem_571:_Gold_Nanoparticles/2012/09/19|Puja Mody]] | |||
*Tris added to Au/BSA | |||
**In order to determine how various concentrations of tris affect AuNPs in solution, tris was added to 70 [HAuCl<sub>4</sub>/BSA] solutions prepared [[User:Michael_F._Nagle/Notebook/Chem_571/2012/09/12|last week]] at .05mM, .5mM, 5mM, 50mM, 100mM, 200mM, 500mM and 1M. These [[User:Michael_F._Nagle/Notebook/Chem_571/2012/09/25|are to be analyzed by UV/Vis]]. | |||
***1M stock solution for tris was made | |||
****1mol/L *.025L = .025mol Tris needed | |||
****.025mol * 121.14g/mol = 3.0285g Tris weighed | |||
***The following calculations were completed to determine how much tris was needed in each solution for concentrations 1M, 500mM, 200mM and 100mM. A serial dilution was done to prepare concentrations .05mM-50mM from the 500mM solution. | |||

*****6mL Tris stock for 1M solution | |||
****200mM*6mL=1000mM*x | |||
*****1.2mL Tris stock for 200mM solution | |||
****100mM*6mL=1000mM*x | |||
