		+	* put 10g of glass beads on the column and set up tubing, pump etc.
		+	* let system run with about 5ml/min flow rate and 70% ethanol for 10 min

		+	* stop pump and close tube comming behind the column
		+	* add cells to column and let stand for 15 min

		+	* add 50 ml fresh medium (by hand) to the column and let run thru quickly to wash
		+	* add Whatman filter paper on top of the glass beads

		+	* grow strain NK9386 in 5 ml of your medium (the same as used for the bady cell column) over night
		+	* start a 1 l culture in 2 l plastic flasks (the sticky cells would stick to a glas flask!)
		+	* at OD ~0.2 add 1 ml of 100mM IPTG and let grow for one more hour at low shaking (100rpm)
		+	* centrifuge 10 min at 3000rpm at room temperature
		+	* leave about 25ml medium on the pellet and resuspend cells
		+	* add cells to the glass beads on the column (see below)

New page

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.
