Estimation of iron content of encapsulated MM-labelled cells.

Weight of MM; (kDa)	Weight of MM (pg); ()	Iron oxide (%); ()	Iron oxide per MM (pg); ( = × )	MM per cell; ()	Iron content per cell (pg); ( = × )	Cells per capsule; ()	Iron content per capsule (ng); ( × )
7.5 × 10^8	1.24	62	0.77	10.95 ± 1	8.43 ± 1	~6000	50 ± 6

MM: magnetic microspheres; values = mean ± SD.
Data obtained from bangs laboratories.
Estimated by calculating the total number of cells divided by the total number of capsules produced.
