Sterile Agar Plate Preparation and Seed Placement
Materials
- sterile seed in deluted agar
- sterile agar media
- sterile hood environment
- P1000 pipeter
- blue pipeter tips
- plates
- parafilm tape
- 70% ethanol solution in spray bottle
- grid template for desired seed alignment (to be placed under transparent media and referenced during seed placement)
Methods
Pouring Agar
- sterilize items one by one with 70% ethanol spray, placing each item into sterile hood after being sprayed.
- once all are in hood, remove aluminum foil wrap from agar flask.
- emove lid off first plate and keeping the lid between you and the open plate, pour agar into plate. Fill to halfway point, carefully avoiding air bubbles in media. Place lid right-side-up on hood surface, then set poured plate on top. Allow to cool before replacing lid as to avoid condensation.
- Repeat for remaining plates.
Seed Placement
- draw horizontal line across plate with a center point roughly one inch from the perimeter of plate
- place reference grid (link to pic or file) under plate, matching horizontal lines.
- set pipeter to small volume(?) so that when fully ,
- on firm agar
- don't fill too much, use finger press method
Notes
Keep head out of hood. Contamination from hair, mouth, nose, hands, etc. will infect culture plate with mold spores.
