What are the optimum storage conditions for Alt-R HDR Donor Blocks?

IDT ships Alt-R™ HDR Donor Blocks dry at ambient temperatures. While dry, we recommend long term storage at -20°C. After resuspending in a high quality, molecular-grade water or buffer, pH 7.5-8.0, the Alt-R HDR Donor Blocks should be stored at 4°C for short term, or –20°C for long-term storage. We do not recommend diluting Alt-R HDR Donor Blocks to low concentrations (<10 ng/µL) due to yield loss resulting from adherence of the material to the plastic tube.
