While we continue to maintain our legacy In-Fusion HD Cloning kits and systems, we strongly recommend that you switch to the more recently developed In-Fusion HD Cloning Plus products and the In-Fusion HD EcoDry Cloning Plus products. These newer versions provide the same robustness and reliability you have come to expect from In-Fusion technology but have been optimized to include all the necessary components for your cloning workflow, thereby providing more accurate and efficient results.
