Phage-Phenotype Imaging of Myeloma Plasma Cells by Phage Display
Multiple myeloma (MM) is a malignant disease based on differentiated plasma cells (PCs) in the bone marrow (BM). Flow cytometry and fluorescence microscopy, used to identify a large combination of clusters of differentiation (CDs), are applied for MM immunophenotyping. However, due to the heterogene...

Our results highlight the possibility of using a phage-fluorescence probe for the simultaneous examination of the presence/absence of CDs associated with disease usually detected by combination of anti-CD antibodies. The design of a multi-phage imaging panel could represent a highly sensitive approach for the rapid detection of immunophenotype subtypes and the subsequent characterization of patient disease status.https://www.mdpi.com/2076-3417/11/17/7910phage display selectionmultiple myeloma (MM)FITC-labelled phagefluorescent imagingimmunophenotype identification |
