ABSTRACT: Microscale cell surface capture of RPMI 1788 cells
Project description:A detergents assisted glycoprotein capture method was developed to increase the coverage of N-glycoproteome of various samples.Application of this approach in the larger scale N-glycoproteomics analysis of the HEK 293 cell membrane led to the identification of 2253 unique N-glycosites from 953 proteins. Application of this approach to human serum resulted in the identification of 850 N-glycosylation sites without any immuno-depletion and fractionation.
Project description:Detailed knowledge of cell surface proteins for isolating well-defined populations of human pluripotent stem cells (hPSCs) would significantly enhance their characterization and translational potential. Normal H9 human embryonic stem cells and the KB3 human induced pluripotent stem cell lines were analyzed by Cell Surface Capture Technology, and in parallel transcript profiles from five independent samples (i.e., Replicas 1-5 for each) were performed to facilitate protein and transcriptomic comparisons. The study compared gene expression profiles of pluripotent stem cells with Cell Surface Capture technology generated N-glycoprotein surfaceome analyses of the same cell types.

Project description:Trypanosoma brucei Lister 427 bloodstream forms were cultured in HMI-11 medium. Total RNA was prepared using Qiagen RNAeasy kits for single sample RNAseq to estimate VSG mRNA abundance (and not to reconstruct the transcriptome). The cDNA libraries were prepared and sequenced at the Beijing Genomics Institute (Shenzhen, China). Polyadenylated RNA was purified from total RNA, converted to cDNA using random hexamer primers sheared and size selected for fragments ~200 bp in length using the Illumina TruSeq RNA Sample Preparation Kit v2. RNAseq of the resulting libraries was used for the determination of transcript abundances. Sequencing was performed on an Illumina Hiseq 2000 (Illumina, CA) platform and 90 base paired end reads obtained. Four samples were analysed: 1. Trypanosoma brucei Lister 427 expressing VSG2 2. Trypanosoma brucei Lister 427 expressing VSG6 3. Trypanosoma brucei Lister 427 expressing VSG6 and a VSG2 transgender located in the active bloodstream expression site 28 days after electroporation 4. Trypanosoma brucei Lister 427 expressing VSG6 and a VSG2 transgender located in the active bloodstream expression site 44 days after electroporation.
