Category: Protein Protocols: Protein Extraction From Cells

Cell Lysate Extracts. Great protocols for cell lysis preparation from a variety of cell types. There are numerous methods of cell stimulation and lysis. For a given protein, Upstate’s Laboratories determine the specific treatment upon initial testing of its products. It is important to select the correct cell line, stimulation procedure (if any), and lysis protocol. Upstate. - [Read Cell Lysate Extracts]

Category: Transfection Protocols

Protocol should be viewed as a starting point for systematic optimization of transfection mediated by lipofecting agents. Once a positive signal has been obtained from a transfected plasmid carrying a standard reporter gene, optimal conditions for transfection can be established by systematic variation of parameters such as the initial cell density, the amount and purity of DNA, the media and serum, and the time of exposure of the cells to the cationic-lipid-DNA complex. - [Read DNA Transfection Mediated by Lipofection Protocol]

Flow assays offer visualization of cell adhesion under wall shear stress. Visualization of the different events of cell adhesion can be quantified by selective image acquisition and subsequent image processing. Flow assays are suited for adhesive events which occur very rapidly in a time scale shorter than that of most static adhesion assays. Also, events subsequent to the initial events can be studied such as cell stabilization and spreading giving some insight into the kinetics of cell-cell. - [Read Dynamic Flow Assay for Cell Adhesion in a Parallel Plate Flow Chamber]

Category: Cell Biology and Cell Culture: Cell Adhesion Protocols

Flow assays allow visualization of cell adhesion under well-defined wall shear stress. Visualization of the events of cell adhesion are quantified by selective image acquisition and image processing. Events subsequent to the initial events can be studied such as cell stabilization and spreading. John T. Patton~GlycoTech Corporation, Rockville, Maryland - [Read Dynamic Flow Assay in a Parallel Plate Flow Chamber]

Category: Developmental Biology: Utilizing Model Organisms Protocols

In the experiment there are three players A, B, and C. Player A gets an initial endowment of 10, player B gets 0 and player C gets 5 points. First, player A decides how many of his 10 points to transfer to B. Then, player C observes the decisions of A and gets the possibility to leave the payoffs unaffected or to punish A by deducting 3 (or 6) points from A at a cost of 1 point (or 2 points) for C.... - [Read Experiments on Parochial Altruism in Humans; Procedures and Instructions]
