Proteins of FBS serum granulations and nanobacteria identified by MALDI-TOF mass spectrometry.

aThe values shown for each protein correspond to the number of unique
peptides identified for each protein which was divided by the total
number of peptides obtained for the first 50 proteins obtained in
one sample. This value was then multiplied by 100 to reflect the
relative abundance of each protein (see the text for more
details).
bMW: molecular weight.
cSerum granulations (pellets) were obtained from untreated FBS (FBS-1)
or following addition of either CaCl2 (FBS-2),
Na2HPO4 (FBS-3), or both (FBS-4) as
described in the Materials and Methods.
dThe different NB samples presented here were all obtained from FBS as
described in the Materials and Methods.
