Latex beads, deep blue dyed

Latex beads have been used to study the regulation of primary mesenchyme cell migration in the sea urchin embryo and to gain a better understanding of the role of ecto-NAD+ glycohydrolase, an enzyme predominantly associated with phagocytic cells. Latex beads have also been used to develop a new technique for measuring the plaque-forming cell (PFC) responses to bacterial antigens.
