GrowingOvernightCultures

1. Place 2 mL of the appropriate sterile medium in a 13 mm yellow-capped culture tube. If more culture is needed, place up to 5 mL in a 16 mm green-capped culture tube. Large amount of culture should be made in growth flasks, using up to 25 flask volume in medium (e.g., no more than 30 mL in a 125 mL flask, or 250 mL in a 1000 mL flask).2. Touch a single colony with the end of an applicator stick and hold it in your ......阅读全文
