Entry title Objective Learn how to maintain an OpenWetWare Notebook. Description Place three test tubes in a water bath at 80C test tube 1: 50 uL BSA 50 uL HAuCl water test tube 2: 50 uL HAuCl 100 uL BSA water test tube 3: PCR tube equal parts BSA and HAuCl After two hours start to cool bath using ice Place three test tubes in heat block at 80C test tube 1: 50 uL BSA 50 uL HAuCl water test tube 2: 50 uL HAuCl 100 uL BSA water test tube 3: PCR tube equal parts BSA and HAuCl Place test tube in PCR run at 80C for two hours then decrease 2C every 2 min until the sample reaches room temperature Run microwave reaction with 400 uL BSA 400 uL HAuCl and water to the top (about 8 mL) at 300 W 80C 30 min Allow full cool down time Data This data showed that increasing the ratio of BSA/gold will prevent the formation of purple protein fibers. Notes After an hour purple fibers appear in the dilute solution in the heat block; the small tube and less Au samples have purple solution Hour and a half: PCR tube in heat block has fibers Two hours: purple solution in the less Au sample
