Introduction to Flow Cytometric Analysis | Flow Cytometry
网页The staining is positive when the fluorescence of any given marker is greater than that of the negative control (internal negative or isotype control). In general, positive staining can be categorized as dim, moderate, bright or variable. Dim staining is defined as slightly increased when compared to the negative control.

网页2020年4月6日 · The CD45 dim CD34 + CD38 − CD133 + cells are prominently detected in bone marrow of patients with AML and CML. As shown in Fig. 1 , the CD45 dim CD34 + CD38 − CD133 + cells were examined by four-color flow cytometry in diverse hematological malignancies including AML ( n = 40), CML ( n = 6), DLBCL ( n = 19), MM ( …

网页2018年4月1日 · Using CD45 isoforms to identify cells as being leukocytes is a long known technique and CD45 bright lymphocytes can easily be distinguished from CD45 dim monocyte/myeloid cells in flow cytometry. In more recent studies, new cell types were found with distinct CD45 co-expression patterns.

网页The CD45-dim area is often the gating strategy used to identify and phenotype blasts in multiple tubes and is useful and convenient in most samples. However, one should consider the presence of non blasts" as possible heterogeneous populations in this CD45-dim area in order to avoid erroneous results.

网页2015年9月2日 · A: Myelomonocytic progenitors are located in the CD45 dim /SSC dim population (blue). The myelomonocytic progenitors can be selected by plotting CD34 against CD117 (see red arrow). Immature cells differentiate from CD34 − /CD117 − into CD34 + /CD117 + (myeloblasts) and into CD34 − /CD117 + (promyelocytes).

网页2024年9月11日 · Blast cells, including myeloblasts or lymphoblasts, have a dim-to-moderate CD45 expression and low side scatter. The latter is because of the higher nuclear-cytoplasmic ratio and scant cytoplasm. These cells constitute ≥20% of peripheral blood or bone marrow. The differential counts in flow cytometric …

网页2020年4月6日 · Methods: We examined the levels of CD45 dim CD34 + CD38-CD133 + cells in bone marrow samples from patients with hematological malignancies and healthy controls, using four-color flow cytometry. Results: Interestingly, the CD45 dim CD34 + CD38 - CD133 + cells were highly expressed in the bone …

网页2020年10月10日 · CD45 is a transmembrane phosphatase that functions in T cell activation and signaling. Multiple CD45 isoforms are simultaneously expressed on T cells due to alternative splicing of three exons that correspond to extracellular domains A, B, and C or the exclusion of all three (CD45RO).
