Pre-PCR and Post-PCR Areas

Use the following guidelines to avoid cross-contamination.

Establish a pre-PCR area for pre-PCR processes.
Establish a post-PCR area for processing PCR products.
Do not use the same sink to wash pre-PCR and post-PCR materials.
Do not use the same water purification system for pre-PCR and post-PCR areas.
Store supplies used for pre-PCR protocols in the pre-PCR area. Transfer them to the post-PCR area as needed.
