In recent years, immune checkpoint proteins in the tumor microenvironment have been under intense study. If you work in the immuno-oncology field, chances are you are either performing multiplex IHC (mIHC) or would like to. Ultimately, a multiplexed image like the one featured here provides a multi-layered depiction of a tumor, such that each antibody corresponds to a different fluorescent signal. If you want to detect more targets in your IHC, but aren’t sure how to design a panel of antibodies and fluorophores for mIHC, we’ll walk you through the process in this post.

Research trends in macrophage plasticity

It’s an exciting time for immuno-oncology research, as potential predictive biomarkers from an expanding collection of cell types are being pursued. Explore the plasticity of tumor-associated macrophages (TAMs) and challenges in distinguishing M1- versus M2- functional states in this 5-minute video featuring CST Developmental Scientist Sarah Klein, PhD.

Multiple myeloma (MM) is a type of hematopoietic malignancy characterized, in part, by bone pain, anemia, kidney failure, and recurring infections. The underlying mechanism that drives the disease is abnormal proliferation and accumulation of malignant plasma cells in the bone marrow that secrete large amounts of abnormal antibodies.
