Tandem Affinity Purification of SBP-CBP-tagged Type Three Secretion System Effectors
[Abstract] Identification of protein-protein interactions of bacterial effectors and cellular targets during infection is at the core to understand how bacteria manipulate the infected host to overcome the immune response. Potential interacting proteins might be identified by genetic methods, i.e., two hybrid screens and could be verified by ...
Measurement of Dopamine Using Fast Scan Cyclic Voltammetry in Rodent Brain Slices
[Abstract] Fast scan cyclic voltammetry (FSCV) is an electrochemical technique that allows sub-second detection of oxidizable chemical species, including monoamine neurotransmitters such as dopamine, norepinephrine, and serotonin. This technique has been used to record the physiological dynamics of these neurotransmitters in brain tissue, including their ...

[Abstract] Cell synchronization is widely used in studying mechanisms involves in regulation of cell cycle progression. Through synchronization, cells at distinct cell cycle stage could be obtained. Thymidine is a DNA synthesis inhibitor that can arrest cell at G1/S boundary, prior to DNA replication. Here, we present the protocol to synchronize cells at ...
3D Culture Protocol for Testing Gene Knockdown Efficiency and Cell Line Derivation
[Abstract] Traditional 2D cell cultures with cells grown as monolayers on solid surface still represent the standard method in cancer research for drug testing. Cells grown in 2D cultures, however, lack relevant cell-matrix and cell-cell interactions and ignore the true three-dimensional anatomy of solid tumors. Cells cultured in 2D can also undergo ...
Quantitative Live-cell Reporter Assay for Noncanonical Wnt Activity
[Abstract] Noncanonical Wnt signaling functions independently of the β-catenin pathway to control diverse developmental processes, and dysfunction of the pathway contributes to a number of human pathological conditions, including birth defects and metastatic cancer. Progress in the field, however, has been hampered by the scarcity of functional assays for ...

[Abstract] Reactive oxygen species (ROS) are generated during normal metabolic processes under aerobic conditions. Since ROS production initiates harmful radical chain reactions on cellular macromolecules, including lipid peroxidation, DNA mutation, and protein denaturation, it has been implicated in a wide spectrum of diseases such as cancer, ...
Mouse Phrenic Nerve Hemidiaphragm Assay (MPN)
[Abstract] The neuromuscular junction (NMJ) is the specialized synapse by which peripheral motor neurons innervate muscle fibers and control skeletal muscle contraction. The NMJ is the target of several xenobiotics, including chemicals, plant, animal and bacterial toxins, as well as of autoantibodies raised against NMJ antigens. Depending on their ...
