Immunohistochemistry News and Research

RSS

Immunohistochemistry (IHC) is an imaging technique to visualize antigens in cells. Labeled antibodies bind to target antigens in the cell to image the distribution and localization of specific proteins of interest

Clinical trials – how can patients get the most benefit out of them?

Putting patients at the centre of clinical trial research is perhaps something that goes without saying. At the Clinical Innovation and Partnering World congress in London last week, this was much discussed, along with the need to increase efforts into engaging patients to take part in clinical trials, and the fact that patients are sometimes suspicious of research because it is not explained enough and patient engagement is poor.

Johns Hopkins researchers find no evidence of CMV in aggressive brain cancer tissues

In a rigorous study of tumor tissue collected from 125 patients with aggressive brain cancers, researchers at Johns Hopkins say they have found no evidence of cytomegalovirus (CMV) infection and conclude that a link between the two diseases, as claimed by earlier reports, likely does not exist.

HC-based NGS helps detect genomic alterations not identified in routine lung cancer screening

The use of hybrid capture-based (HC-based) next-generation sequencing (NGS) to identify targetable oncogenic drivers in patients with lung adenocarcinoma results in the detection of genomic alterations (GAs) not identified in routine screening, and impacts treatment decisions and clinical outcomes.
