A newly developed method for the isolation of human motile spermatozoa using density-gradient centrifugation was compared with the traditionally used Percoll technique. Sperm samples were divided into two equal aliquots, which were purified with either the traditionally performed Percoll technique

To measure intestinal absorption of macromolecules we have developed a new technique employing synthetic polysucrose polymers as probe molecules. Polysucrose (PS) is water-soluble, nontoxic, resistant to intestinal enzymes, spherical and can be produced with a molecular weight distribution that relates

The extracellular matrix glycoprotein thrombospondin-1 (TSP1) inhibits angiogenesis, endothelial cell growth, motility and adhesion. Peptides from the type I repeats of TSP1 mimic the adhesive and growth inhibitory activities of the intact protein and specifically interact with heparin and transforming
Centrifugation enables the separation of particles by sedimentation. Learn how to separate particles using a centrifuge and how to use Stokes' law to calculate the velocity of sedimentation.
