Cold storage and cryopreservation of hops (Humulus l.) shoot cultures through application of standard protocols.
The USDA-ARS National Clonal Germplasm Repository (NCGR) stores the global diversity of Humulus for the US Plant Germplasm System as trellised plants in a field genebank. In vitro storage and cryopreservation are now considered excellent ways to provide medium and long-term storage for plant collections. Developing a new cryopreservation or cold storage protocol for every accession or genus of ...

15 صفحه اولViral studies on human brain culture retrieved from cold storage.
Tissue cultures established from brain tissues of six patients with various chronic, degenerative diseases did not show evidence of viral agents. Sucrose gradient analysis of radioactively labeled culture fluid from two patients failed to reveal the presence of any incomplete or defective virus. Extracellular fluids from three brain cultures contained a factor able to stimulate deoxyribonucleic...
متن کاملGenetic and epigenetic stability of cryopreserved and cold-stored hops (Humulus lupulus L.).
Conventional cold storage and cryopreservation methods for hops (Humulus lupulus L.) are available but, to our knowledge, the genetic and epigenetic stability of the recovered plants have not been tested. This study analyzed 51 accessions of hop using the molecular techniques, Random Amplified DNA Polymorphism (RAPD) and Amplified Fragment Length Polymorphism (AFLP), revealing no genetic variat...

We have constructed a compact purely electrostatic ion-beam trap, ConeTrap, which we have mounted inside a double-walled vacuum chamber. In the inner vacuum chamber, we can obtain ultra-high vacuum (UHV) conditions and reach thermal equilibrium at well controlled temperatures down to 10 K. The chamber was constructed partly with the purpose of making high-precision measurements in ConeTrap, but...
