Prepare samples for flow cytometry: Label cells with a flourescent marker that can be detected by a flow cytometer. some of my data is negative. Fluorescence for hTERT-Alexa 647 is quantitatively expressed here as the ratio of median fluorescence intensity in CD34 + progenitor cells compared with that in the reference population of lymphocytes in the CD45 + population from the same sample. An alternative approach that is closer to absolute quantitation of binding sites for individual mAbs is use of the so-called "antigen-binding capacity" (or ABC) beads. The use of messenger RNA (mRNA) for vaccination (1, 2), protein replacement therapy and cancer immunotherapy (), and mRNA technology encoding CRISPR/Cas nuclease for genome editing holds the potential to revolutionize the treatment of a wide range of currently untreatable genetic diseases.The US Food and Drug Administration (FDA) recently authorized two mRNA Traxler et al.
