I made up three separate solutions of M9 minimal media adding the components in the following order (total volume 200ml) and then adjusted the pH to 7, 7.4 and 7.8 Reagents and Solutions The following reagents and solutions are required for all four LiAc/SS-DNA/ PEG protocols. Lithium Acetate (1.0 M). Dissolve 5.1 g of lithium acetate dihydrate (Sigma Chemical Co. Ltd., St. Louis, MO) in 50 ml of water, sterilize by autoclaving for 15 min, and store at room temperature. Let autoclave bags accumulate: Avoid allowing autoclave bags to accumulate in the lab, autoclave, or autoclave room. Regular disposal and maintenance are necessary to ensure a clean and efficient workspace. Use autoclave bags for non-biohazardous waste: Autoclave bags should only be used for the collection of biohazardous waste. Utilizing them .
The procedure takes up to 1.5 h, depending on the length of heat shock, once the yeast culture has been grown. This method is useful for most transformation requirements. During the test, the spore strip is placed in the center of the load or material to be sterilized within the autoclave. The autoclave cycle is then initiated, subjecting the spores to the specified time and temperature parameters. After the cycle, the inner ampule of the vial is broken, releasing the growth medium.

Autoclave - Download as a PDF or view online for free. . Gas autoclaves:Also known as chemicalves, gas autoclaves use a vapor solution to sterilize its contents. Formaldehyde gas and Ethylene oxide are the sterilizing agents used in gas autoclaves. They consume lesser heat and take lesser time to complete the cycle. Ultraviolet autoclaves . 10 × LiAc stock solution (1 M): Dissolve 10.2 g lithium acetate in 100 mL of deionized water, adjust to pH 7.5 with dilute acetic acid, autoclave for 15 min, and store at RT. 3. 50% (w/v) PEG3350 stock solution: Dissolve 50 g PEG3350 in about 30 mL of deionized water, stir until it dissolves and make up the volume to 100 mL, autoclave for 15 .IV. Solutions Required for Yeast Transformation • 1.1X TE/LiAc Solution Prepare fresh just prior to transformation using the stock solutions provided. Combine 1.1 ml of 10X TE Buffer with 1.1 ml of 1 M LiAc (10X). Bring the total volume to 10 ml using sterile, deionized H 2 O. • PEG/LiAc Solution (polyethylene glycol 3350/lithium acetate) Autoclave at 121 °C for 15 min.

7. INSTRUCTIONS Do not over load the autoclave. Use appropriate temperature and pressure. The lower the temperature, the longer the exposure time required for sterilization. Remove all the air from the autoclave before introducing steam because air is heavier than steam and will reduce the steam concentration (and hence the effectiveness) of the sterilization. .YEPD liquid: 10 g yeast extract (US Biologicals), 20 g peptone (US Biologicals) are dissolved in 950 mL water.
