A new antibody library developed by PNNL scientists can identify antibodies in days, reducing labor costs and improving the design of medical treatments. The library, which contains 1 billion human antibodies, uses a yeast surface display method to quickly screen for useful antibodies.
Researchers found that exposing rats to low levels of carbon monoxide significantly reduced intimal hyperplasia and leukocyte accumulation, indicating a protective effect against arteriosclerosis. The study suggests potential therapeutic benefits for treating vascular diseases.
Scientists have achieved germline transmission of 'gene knockdown' in mice by using genetic engineering to create mouse embryonic stem cells targeted with RNAi. This enables the manipulation of gene activity in specific tissues and allows for switching on and off at any time during development or adulthood.
