However, because NL119 was a nonencapsulated strain originally recovered from a single colony and well-isolated by repeated passages in vitro, and no encapsulated subpopulation was ever retrieved in vitro by the selection using Percoll density gradient centrifugation
, the most plausible hypothesis would be that the capsule-recovered S.

Cattle spermatozoa membrane function changes on gender selection process using Percoll density gradient centrifugation
Phagosomes from infected cells were isolated by sucrose density gradient centrifugation
for biochemical characterization.
Phagocytosis and separation of hemocytes by discontinuous density gradient centrifugation
were also studied.
Peripheral blood mononuclear cells (PBMCs) were separated by Ficoll-Hypaque density gradient centrifugation
from fresh heparinized blood collected by venipuncture from healthy, nontransfused consenting volunteers, as previously described (Boyum 1968; Waldman et al.
Using sucrose density gradient centrifugation
to detect complex formation, we have shown that recombinant C8a MACPF is capable of binding C8b and C8g.
85 M sucrose) just prior to density gradient centrifugation
Linear gradient makers can make reproducible gradients up to 2000mls total volume and are designed for use in gradient gel electrophoresis, sucrose density gradient centrifugation
and liquid chromatography.
