To obtain more insight into the effects of DBZ on proliferation in the different fractions of the colonic crypt, we performed a fractionation of colonic epithelial cells from the surface (fraction 1, named F1) to the base of crypts (fraction 3; F3).
We explain the correlated behavior of Mg/Ca and Sr/Ca outside the central band by Rayleigh fractionation from a closed pool, an explanation that has been proposed elsewhere, but which is tested in this study by a simple and general relationship.
The copolymers obtained at different conversion and Al/Ti ratio were isolated to a series of fractions by stepwise isothermal crystallization fractionation from 80 °C to −20 °C.
(A ) Experimental design depicting biochemical fractionation from the IC after behavioral training.
Mitochondrial fractionation from cultured cells was performed with a Mitochondrial Isolation kit (Thermo Scientific) as described in the manufacturer's instructions.
Human IgG fractions were first isolated with 33% ammonium sulphate fractionation from plasma of patients with APS and from healthy donors as previously described [ 21, 22].
Partial melting of the continental SSC ultramafic metasomes also represents a different way of crustal growth and crust-mantle interaction with element fractionation from that in the much better studied case of arc volcanism above oceanic subduction zones.
iISGs and mISGs were obtained by subcellular fractionation from INS-1 cells.
The star-shaped block copolymers were isolated by precipitational fractionation from aspolymerized crude products using benzene-methanol mixtures.
Area confined by large-dash line depicts values for sulfur isotopes fractionation from this work in all springs and pools except DS.
