Equipment

  • Serological pipette controller (e.g. battery-powered pipetting aid ROTILABO, cat. no. TC16.1)

Protocol

1. Prepare the buffer in a 500 ml square media bottle by adding the following reagents. Use the glass pipette for transfer of large volumes (> 1 ml). Mix reagents by shaking the bottle.

Note
[Labeling]

Label the bottle with the buffer name, batch ID, date and the initials of the person who prepared the buffer. Include lot number of AmpliTaq Gold buffer.

Attention: Every single bottle prepared at the same day gets a new batch ID. Name the batches with Roman numerals (e.g. batch I, batch II, etc.)

2. Store the buffer at room temperature until used. Shelf life is at least one year from preparation.

Note
