Cell Biology and Cell Culture

Protocol applies EFs to cells in vitro but has been modified and to use electrotactic chambers to accommodate cells growing in planar culture or in three-dimensional (3D) gels, en bloc tissue cultures in 3D and possible small embryos, such as that from frog and zebra fish. The EF is applied to the cells or tissues cultured in a customer designed electrotactic chamber via agar salt bridges, Steinberg’s solution and Ag/AgCl electrodes. - [Read Application of Direct Current Electric Fields to Cells and Tissues in vitro]

Techniques on how to create gradients of iodixanol for the fractionation of mammalian cells. These gradients can be generated as pre-formed discontinuous or continuous gradients. These gradients are invariably run in swinging-bucket rotors in low-speed centrifuges. - [Read C2 Preparation of pre-formed iodixanol gradients for mammalian cells.]

OptiPrep Application sheet C14 describes procedures for determining the density and sedimenting properties of any cell (of any size or density) using either a continuous or discontinuous gradient of iodixanol. This Application Sheet describes procedures aimed at isolating specifically a relatively low-density cell fraction from any tissue. - [Read C25 Isolation from spleen, thymus, pancreas, alveolar tissue and other tissues]

The protocol presented in this Application Sheet uses an alternative strategy to sedimentation on to a density barrier, that is to adjust the density of whole blood to a value just greater than the cells of interest and allow them to float to the surface. - [Read C8 Isolation of bovine peripheral blood mononuclear cells by flotation.]

This chemotaxis assay protocol is based on the premise of creating a gradient of the chemotactic agent and allowing cells to migrate through a membrane towards the chemotactic agent. A chemotaxis assay can determine whether your protein or small molecule of interest has chemotactic activity on a specific cell type. Chemotaxis is then the ability of a protein to direct the migration of a specific cell. - [Read Chemotaxis Assay 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]

Cell fractionation of cellular components using Percoll a synthetic, colloidal solution of polyvinylpyrrolidone coated silica, specifically designed for sedimentation centrifugation. Percoll becomes a simple matter to establish a linear density gradient. Organelle separations are much easier to accomplish on Percoll density gradients than on sucrose gradients. - [Read Equilibrium Density Gradient Percoll Protocol]

Purification protocols of the viruses: HIV-1, Lassa virus, oncornavirus and other retroviruses. Protocol uses an iodixanol gradient in a sedimentation velocity mode to purifyHIV-1 virions without affecting the infectivity of the virus. In rate-zonal iodixanol gradients the HIV-1 was effectively separated both from Vif and from the microvesicles. - [Read M5 Velocity (rate zonal) gradients for purification and assembly analysis of viruses.]

Tubulin Polymerization Protocol using GTP and GMPCPP

Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.
