However, this is a link to electronic documents available in the Federal Register through the GPO Access web site, not EPA- specific proposed rules, and the viewer is then required to use that site's search tools to identify particular proposed rules.
For new commercial chemicals, toxicity testing in animals should be required before they are marketed.
An example of a policy was that units were required to use commercially developed software rather than developing unique software inhouse.
To determine if extracellular Ca 2+is also required for MTX-induced membrane blebbing, changes in cell morphology were correlated with ethidium uptake in the presence of Ca 2+-free extracellular buffer (Fig.
Several lines of evidence suggest that the SCF pathway is also conserved in the fission yeast Schizosaccharomyces pombe . Pcu1p, a Cdc53p/CUL1-related protein, was shown to associate with two different F-box/WD repeat proteins, Pop1p and Pop2p, when overexpressed [ 18 ] . In addition, genetic studies demonstrated that both of these F-box proteins are simultaneously required for efficient destruction of Rum1p and the replication initiator Cdc18p [ 18 19 20 ] . Rum1p is a Sic1p-analogous CDK inhibitor, which accumulates in G1, but is degraded as cells enter S phase [ 21 22 ] . Failure to degrade Rum1p is the major phenotypic defect of pop1 and pop2 deletion strains, which leads to disturbance of normal cell cycle progression, resulting in polyploidy [ 18 19 20 23 ] . Based on the genetic data and the biochemical observation that Pop1p and Pop2p interact when overexpressed, a putative SCF Pop1p-Pop2pcomplex was proposed, which would contain the heterooligomerizing F-box proteins Pop1p and Pop2p bound to SCF core components [ 18 20 ] .
