Background Alzheimer’s disease (AD) pathogenesis involves various immune-related phenomena both in central nervous system and peripheral blood. However, the characteristics of immune cells is poorly defined AD at a single cell level. Method We profile 36,849 blood mononuclear (PBMC) from patients with amyloid positive (Aβ+) normal controls negative (Aβ-) by 5' single-cell transcriptome repertoi...

background: nowadays, highly specific aptamers generated by cell selex technology (systematic evolution of ligands by exponential enrichment) are being applied for early detection of cancer cells. prostate specific membrane antigen (psma), over expressed in prostate cancer, is a highly specific marker and therefore can be used for diagnosis of the prostate cancer cells. the aim of the present s...

background: l1 retrotransposons are the most active mobile dna elements in human genome. unregulated l1 retrotransposition may have deleterious effect by disrupting vital genes and inducing genomic instabilities. therefore, human cells control l1 elements by silencing their activities through epigenetic mechanisms. it has been shown that cell division and heavy metals stimulate the frequency of...

Our single cell analytical experiments for future protein fingerprinting combines microfluidic on-chip protein electrophoresis with latest laser technology for single cell manipulation and (label-free) protein detection, and is presented by the following issues: 1) Single cells were trapped and navigated by optical tweezers (OT) in a PDMS microfluidic device, and lysed at a predefined position....

Abstract Studies of acute myeloid leukemia rely on DNA sequencing and immunophenotyping by flow cytometry as primary tools for disease characterization. However, tumor heterogeneity complicates integration variants immunophenotypes from separate measurements. Here we introduce DAb-seq, a technology simultaneous capture genotype cell surface phenotype single cells at high throughput, enabling di...

Background: Design of experiments is a rapid and cost-effective approach for optimization of recombinant protein production process. In our previous study, we generated a potent dual-acting fusion protein, anti-CD22 scFv-apoptin, to target B-cell malignant cell lines. In the present investigation, we report the effect of different variables on the expression levels of this fusion protein. Metho...

Abstract Multi-analyte single cell technologies have potential to greatly accelerate antibody discovery by identifying antigen-specific B cells. Barcode Enabled Antigen Mapping (BEAM) provides a high-throughput, multimodal analysis of antigen-bound cells (BEAM-Ab) using 10x Genomics Chromium Single Cell Immune Profiling v2 Solution and novel computational approaches discover B-cell receptor (BC...
