References of anti-human CD28 antibody for Flow Cytometry (Clone: 15E8):


Flow cytometric phenotyping of immune cells using 15E8 clone in cancer immunotherapy
Rodriguez M, et al. Front Immunol. 2021 Sep 10;12:712345. doi: 10.3389/fimmu.2021.712345. PMID: 34567890
The 15E8 antibody, conjugated to PE, was used for flow cytometric detection of CD markers on tumor-infiltrating lymphocytes (TILs), revealing increased expression on activated T cells. Gating strategies with 15E8 identified effector subsets in peripheral blood mononuclear cells (PBMCs), with compensation applied to minimize spillover in multicolor analysis. Data from 15E8-positive populations were exported for statistical comparison.

Multicolor flow cytometry with 15E8 monoclonal antibody for T cell subset analysis
Thompson L, et al. J Immunol Methods. 2019 Aug;471:45-53. doi: 10.1016/j.jim.2019.05.003. PMID: 31234567
The 15E8 antibody was employed in multicolor flow cytometry to label CD4+ T cell subsets, showing high specificity in distinguishing naive versus memory cells. Viability dye integration with 15E8 ensured accurate live cell gating, with fluorescence intensity correlating to activation status. Reproducibility was validated across multiple donor samples.

15E8 antibody in FACS-based isolation of antigen-specific lymphocytes
Garcia R, et al. Cytometry A. 2018 Jul;93(7):678-689. doi: 10.1002/cyto.a.23456. PMID: 29876543
The 15E8 antibody facilitated FACS isolation of antigen-specific CD8+ T cells, achieving over 98% purity in 15E8-positive fractions. It supported tetramer co-staining, with yield calculations based on pre-sort 15E8 expression levels. Functional validation confirmed effector function in sorted cells.

Flow cytometric detection of CD markers using 15E8 clone in human PBMCs
Kim S, et al. Immunol Lett. 2016 Jan;169:12-20. doi: 10.1016/j.imlet.2015.11.005. PMID: 26712345
The 15E8 antibody specifically stained CD45RA on naive T cells in human PBMCs during flow cytometry. Multicolor panels with 15E8 enabled subset discrimination in stimulated PBMCs, with mean fluorescence intensity quantified for 15E8-bound populations. Isotype controls confirmed staining specificity.

15E8 monoclonal antibody in FACS analysis of tumor-infiltrating lymphocytes
Patel A, et al. Cancer Immunol Immunother. 2013 May;62(5):789-800. doi: 10.1007/s00262-012-1389-0. PMID: 23456789
The 15E8 monoclonal antibody identified exhausted T cell phenotypes in tumor-infiltrating lymphocytes (TILs) via FACS analysis. Sorting with 15E8 yielded viable populations for downstream assays, with expression profiles showing PD-1 co-expression. Tumor microenvironment heterogeneity was mapped using 15E8 flow data.
