<p class="jove_title">Day 1: Preparing German Glass Coverslips and Seeding Cells</p>
<p class="jove_content"><em>Note</em>: German glass coverslips are often preferable for culturing primary neural stem cells and neurons. We use the following cleaning protocol to improve cell adhesion and spreading. Position coverslips in a small rack that will allow liquid access to both sides of the coverslip. First, incubate coverslips in 1% Liquinox for 10 minutes, followed by 3 washes with deionized water. Make sure that no soap bubbles remain. Next, incub...

<p class="jove_content">This protocol describes an immunostaining procedure for hNSPCs that minimizes the volume of antibody necessary and gives reliable cell staining.  The procedure as described is best for intracellular antigens, but can be modified to stain cell surface molecules or to enhance staining of the cytoskeleton.</p>

immunocytochemistry: human neural stem cells

<p class="jove_content">Immunocytochemistry is a very powerful and fairly straightforward method for determining the presence, subcellular localization, and relative abundance of an antigen of interest, most commonly a protein, in cultured cells.  This protocol presents an easy-to-follow series of steps that will enable researchers to conserve primary and secondary antibodies while getting high quality, reproducible qualitative and quantitative data out of their staining.  There are two aspects of this protocol that help to conserve the volume of antibody necessary for staining.  For one, the cells are grown on small, circular coverslips that are placed in wells of a tissue culture plate.  After fixation, the cells on coverslips can be removed from the wells of the plate. For antibody staining, the coverslip with cells is inverted onto a small drop of antibody solution on parafilm and is covered with a second piece of parafilm to prevent drying.  Using this method, only ~25  &mu;l of antibody solution is needed for each coverslip (or sample) to be stained. This protocol describes immunostaining of human neural stem/precursor cells (hNSPCs), but can be used for many other cell types.</p>
