    Whole-mount Senescence-Associated Beta-Galactosidase (SA-β-GAL) Activity Detection Protocol for Adult Zebrafish
    Authors:  Marta Marzullo, Mounir El Maï and Miguel Godinho Ferreira, date: 07/05/2022, view: 16, Q&A: 0

    Senescence-associated beta-galactosidase (SA-β-GAL) is an enzyme that accumulates in the lysosomes of senescent cells, where it hydrolyses β-galactosides. With p16, it represents a well-recognized biomarker used to assess senescence both

    Quantitative Analysis of Redox Pool (NAD+, NADH Content) in Plant Samples Under Aluminum Stress
    Authors:  Jay Prakash Awasthi, Bedabrata Saha, Hiroyuki Koyama and Sanjib Kumar Panda, date: 06/20/2022, view: 973, Q&A: 0

    Nicotinamide adenine dinucleotide (NAD) is an essential cofactor of numerous enzymatic reactions found in all living cells. Pyridine nucleotides (NAD+ and NADH) are also key players in signaling through reactive oxygen species (ROS), being crucial

    Patterned Substrate of Mobile and Immobile Ligands to Probe EphA2 Receptor Clustering
    Authors:  Zhongwen Chen, Kabir H. Biswas and Jay T. Groves, date: 06/05/2022, view: 779, Q&A: 0

    A multitude of membrane-localized receptors are utilized by cells to integrate both biochemical and physical signals from their microenvironment. The clustering of membrane receptors is widely presumed to have functional consequences for subsequent

    Investigation of Transposon DNA Methylation and Copy Number Variation in Plants Using Southern Hybridisation
    Authors:  Vivek Hari Sundar G. and P. V. Shivaprasad, date: 06/05/2022, view: 504, Q&A: 0

    Plant genomes are pronouncedly enriched in repeat elements such as transposons. These repeats are epigenetically regulated by DNA methylation. Whole genome high-depth sequencing after bisulfite treatment remains an expensive and laborious method to

    In vitro Assays to Evaluate Specificity and Affinity in Protein-phospholipid Interactions

    Protein–lipid interactions play important roles in many biological processes, including metabolism, signaling, and transport; however, computational and structural analyses often fail to predict such interactions, and determining which lipids

    Preparation of Cas9 Ribonucleoproteins for Genome Editing
    Authors:  Sheng-Wei Lin, Viet Quoc Nguyen and Steven Lin, date: 05/20/2022, view: 1332, Q&A: 0

    Genome editing by the delivery of pre-assembled Cas9 ribonucleoproteins (Cas9 RNP) is an increasingly popular approach for cell types that are difficult to manipulate genetically by the conventional plasmid and viral methods. Cas9 RNP editing is
