- Description
- Description: The 2D1 monoclonal antibody reacts with all isoforms of human CD45, also known as Leukocyte Common Antigen (LCA). CD45 is expressed by all hematopoietic cells excluding circulating erythrocytes and platelets. The cytoplasmic portion of CD45 has tyrosine phosphatase enzymatic activity and plays an important role in activation of lymphocytes. Applications Reported: This 2D1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 2D1 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.25 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Fig. 2 In silico validation of the immune cell scoring method. a In silico validation of immune cell scores using simulated mixing proportions. RNA-Seq profiles of FACS-sorted NK cells, macrophages, CD 4 + and CD 8 + T cells, and non-immune CD 45 - cells were mixed with known proportions to obtain a ""clean"" mixture. Noise was added at varying SNRs. Mixing levels were then inferred by ssGSEA from the ""clean"" and noisy mixtures. The Spearman correlations between the simulated and inferred levels ( top panel ) and the bootstrap p values for these correlation values ( bottom panel ) are shown on the y-axes (Additional file 1 : Figure S18 and "" Methods "" for the calculation of the bootstrap p values). b Validation of IIS with methylation-based leukocyte fractions. Spearman correlations between the two orthogonal scores are shown on the x-axis for 13 tumor types. c Validation of TIS with TCR beta chain abundance. Both scores are computationally inferred from RNA-Seq data but employ different approaches to measure T cell levels. Spearman correlations are shown on the x-axis for 19 tumor types

A) The representative figures for isotype control for monocytes gating; live monocytes were gated from FSC/SSC gating. Then CD45+ were gated using the basal level of CD45 Isotype and analyzed for CD14 and HLA-DR expression with respective CD14 and HLA-DR Isotypes.
