November is National Alzheimer's Disease Awareness Month and research into a cure for the disease is vigorous. In a recently published paper "CRISPR/Cas9-Correctable mutation-related molecular andphysiological phenotypes in iPSC-derived Alzheimer’s PSEN2N141I neurons" researchers used the Celigo image cytometer upstream of CRISPR/Cas9 to visualize and asses cell death related to the sensitivity of iPSC-derived PSEN2N1411 neurons in the presence of Aβ42 oligomer toxicity.
Introduction Chinese hamster ovary (CHO) cells are the cell type of choice for biopharmaceuticals due to their propensity to correctly fold and post-translationally modify human proteins . Here, researchers use an optimized bioinformatics tool (“CRISPy”) to generate chimeric RNA called “single guide” RNA (sgRNA) in order to disrupt FUT8, a gene that is utilized in N-glycosylation. This novel web-based tool ensures efficient, fast, and low-cost genetic manipulation of CHO cells for future biopharmaceutical applications. Materials and Methods Cell culture and transfection of CHO cells CHO cells were cultured and transfected by Nucleofector Kit V with 1 μg of Cas9 plasmid [...]
