Recently, American researchers have invented a new type of cancer diagnostic machine that analyzes cancer proteins and tracks treatment effects by analyzing smaller samples, such as a drop of blood or a small piece of tissue in the body. Scientists say the new technology marks the end of a surgical biopsy, which usually involves removing large pieces of body tissue and using anesthesia.
It is understood that this new type of cancer diagnostic machine was invented by researchers at Stanford University. They use the charge of cancer-associated proteins to distinguish these cancer proteins, and the charge varies depending on the surface of the protein. Scientists then use antibodies to identify the number and location of different proteins. The new technology is able to detect the activity of cancer genes on common human lymphoma samples and even distinguish between different types of lymphoma. Dean Feels, a professor of oncology at Stanford University who led the study, said that they can not only detect Pico (10-12 g) grades of protein, but also detect subtle changes in protein changes.
Researchers say the system can also be used to monitor cancer treatments faster and more easily. Although the focus of the study is primarily on blood cancer, scientists also hope to apply it to solid tumors, which they are currently using to test brain and neck tumors. The researchers said they have demonstrated the anti-cancer effect of a cholesterol-lowering drug in a lymphoma patient. Moreover, they also found that this technology also works for lymphoma samples from laboratory mice and cultured tumor cells. Shanghai Medical Device Industry Association
