Purpose
Procedure for Protein Extraction and Purification from BL21(DE3) Cells
Speed: 18,000rpm Temperature: 4°C Time elapsed: 2 hours Rotor used:_____
Result for Protein Extraction and Purification from BL21(DE3) Cells
Procedure for E.coli cell Transformation
225rpm 37°C 1 hour
Following reagents were weighted out: 20g of LB Agar powder from Fisher Scientific® 5g of tryptone from Fisher Scientific® 2.5g of yeast extract from Fisher Scientific® 5g of NaCl from Fisher Scientific® 7.5g agar from Fisher Scientific® Above were placed into a 800mL Erlenmeyer flask. 500mL distilled water was added to reagents. The solution was autoclaved under liquid cycle (see 2012/11/03 for protocol for liquid cycle) After cooling to ~50°C, 50mg ampicillin was poured into autoclaved solution, swirled to mix Under sterile condition, the solution was poured into separate petri dish when temperature reaches ~40°C Plates were left under sterile condition to solidify
Results for E.coli cell Transformation
