Myeloid-derived Suppressor Cells (MDSCs) have come to be known as key regulators of the immune system, particularly with their role in promoting tumor progression. At least two major subsets of MDSCs have been defined in mouse models based on phenotypic features - monocytic-MDSCS (M-MDSCs) and polymorphonuclear-MDSCs (PMN-MDSC). Characterization of human MDSCs in cancer patients has revealed a more complicated picture of MDSC subsets. Flow cytometry has been essential characterizing MDSCs and understanding their role in different cancers. Here are three ways flow cytometry has been invaluable to understanding MDSCs.Read the full article »
There comes a moment when the flow cytometry work can be too much. Sometimes it’s the big “make-or-break” experiment that has to go just right, or sometimes it’s the monthly batches of clinical trial samples that have to be handled, on a Saturday, with swift, deft hands, and you’re the only one qualified for the job. That’s when you either break down in tears of exhaustion and frustration, or you consider finding some help. Now most investigators aren’t in a position to hire and train new staff for cytometry work, but there is high quality and reliable alternative - A contract research organization (CRO).
A CRO can carry out your flow cytometry experiments, to you exact specifications, and meet your needs for a single experiment or a multi-year clinical trial. CROs specializing in flow cytometry may be your best option to guarantee high quality and reliable results.Read the full article »
Ploidy is defined as the number of complete chromosome sets in a cell’s nucleus. In animal cells, chromosomes are typically found in pairs and cells are considered diploid. In contrast, plant cells can tolerate higher levels of genome duplication and can exist in various states of polyploidy. Understanding and characterizing ploidy in diverse organisms, from bacteria to mammals, has been greatly facilitated by flow cytometry-based ploidy measurements. Consider these three P’s of ploidy as you decide if ploidy analysis could be a valuable addition to a current or upcoming study.Read the full article »
