The baby cell column is a way of getting synchronized bacterial cells (E. coli) which are at more or less the same point in their cell cycel.

Basic idea

Bacteria are attached to glass beads with there flagella. The protein coding for a specailly sticy flagella is introduced on the chromosome behind an inducible promotor. The glass beads with the cells are than put on a column and medium without inductor is run thru it. The new born cells will than not have a flagella and washed of with the medium. Such cells will be "babies" and at the beginning of the cell cycel.
