Important: Invitrogen restriction enzymes now come with Universal Buffers L, M, H, K, or T (+BSA) instead of REact® Buffers 1-8. Functionally, the enzymes are the same and have been validated for the recommended buffer. Please contact our technical services department immediately if you have questions or concerns.
