چکیده

We describe a method for obtaining synchronously dividing cells of bacteria (Escherichia coli B and K-12 and Bacillus subtilis 168) and fission yeasts (Schizosaccharomyces pombe) by the use of Percoll density gradients.

Buoyant density constancy of Schizosaccharomyces pombe cells.

Buoyant densities of cells from exponentially growing cultures of the fission yeast Schizosaccharomyces pombe 972h- with division rates from 0.14 to 0.5 per h were determined by equilibrium centrifugation in Percoll gradients. Buoyant densities were independent of growth rate, with an average value (+/- standard error) of 1.0945 (+/- 0.00037) g/ml. When cells from these cultures were separated ...

The Significance Application of Indigenous Phytohemagglutinin (PHA) Mitogen on Metaphase and Cell Culture Procedure

Phytohemagglutinin (PHA) is a lectin, obtained from the red kidney bean that binds to the membranes of T-cells and stimulates metabolic activity, cell division, etc. The object of this research was the comparison between self made PHA (Indigenous) and imported commercial one, following conventional and High Resolution Cell Synchronization technique (HRCS) .From each blood sample of healthy indi...

Distribution of chromaffin secretory vesicles, acetylcholinesterase, and lysosomal enzymes in sucrose and Percoll gradients.

Crude chromaffin secretory vesicles, obtained by differential centrifugation, were further purified on isotonic (Percoll) gradients. The chromaffin vesicle fractions recovered from the gradients contain acetylcholinesterase as well as lysosomal enzymes. With the aid of a subsequent sucrose gradient lysosomal enzymes could be removed from chromaffin vesicle fractions, but not acetylcholinesteras...

Isolation technique alters eosinophil migration response to IL-8.

Disparate reports exist on the eosinophil chemotactic capacity of interleukin-8 (IL-8). We hypothesized that the difference is due to the methods used to purify eosinophils. We therefore compared the eosinophilotactic capacity of IL-8 on human cells isolated by Percoll (positive selection) vs. magnetic cell separation system (MACS) (negative selection). Discontinuous Percoll gradients were prec...
