Interactions of halogenated hydrocarbons with soils

Desorption of tetrachloroethene and 1,2‐dibromo‐3‐chloropropane from aquifer sediments

“…The single-point Kp (i.e., ratio of sorbed to aqueous concentrations) was 0.22 L/kg, corresponding to a KO, of 116 L/kg. The KO, in the aquifer sediment compares with a KO, of 284 L/kg in a surface soil containing 2.57% OC [15] and 238 L/kg as an average for 32 soils [28]. Differences in KO, by a factor of two or three among soils are not unusual, considering the variable nature of natural soil organic matter [3].…”

Membrane fragments from cultured endothelial cells for use in screening anti-FGF receptor antibodies

“…The presence of the 80 kDa protein detected on the Western blot could be a native core protein for the FGF receptor on CVECs. Presence of such core proteins in NIH 3T3 cells has been reported (5). The isolation procedure is especially useful in the screening of monoclonal antibodies for FGF receptors, research that is currently underway.…”
