3. We use lots of ASSAYS in Biotech Protein Presence – protein indicators, spectrophotometry, PAGE, Western blot Activity/Function - protein indicators, enzyme activity assays, spectrophotometry Concentration – protein indicators, spectrophotometry, ELISA Stability/Shelf-life or other characteristics DNA Presence – gel electrophoresis (RE Digests & PCR), dot blot tests Concentration – UV spectrophotometry, dot blot tests

4. Genetic Engineering uses Recombinant Plasmids For Amylase Project (Ch 6-9) we trick E. coli cells to take up the amylase gene (on a pAmy plasmid) and express it to make “large” amounts of amylase. PCR and Restriction Digestion each can confirm the recombinant plasmid is “right.”

5. The pAmylase Plasmid (Lab 8b Restriction Digestion) pAmy is about 6700 bp long and contains: The amylase gene (from Geobacillus stearrnothermophilus) >>> can PCR and run a gel to recognize the gene Several restriction enzyme recognition sites including: 1 for HindIII & 3 for BamHI, >>> see evidence of this using restriction digestion and gel electrophoresis. ~40 bp

6. Agarose Gel Preparation (Lab 4i) Determine amount of agarose (g) to use Mix it with 1X TAE (or other electrophoresis buffer) Heat on medium power in microwave until completely dissolved Cool to 65°C Place well comb Pour agarose to about 7 mm thick Allow 10-15 min to cool Add electrophoresis buffer before removing comb

7. The pAmylase Plasmid after RE Digestion Draw in the expected DNA fragments produced during restriction digestion by HinDIII and Bam HI
