A method has been developed for the fractionation of human erythrocyte membranes, using sodium deoxycholate, EDTA, differential ultracentrifugation, and DEAE-cellulose column chromatography. Serologic studies demonstrate the presence of ABO blood gro

KX, an antigen related to the Kell blood group system, is present in trace amounts on normal red cells and is strongly active on the neutrophils of all of 50 persons thus far tested. Normal circulating monocytes are now shown to also bear KX determin

Small concentrations of the adenosine analogue toyocamycin inhibit the maturation of rRNA, but permit the synthesis of other cellular RNA species including 45-S RNA. This hypothesis is supported by the following evidence: 1. 1. The base composition o

The interaction of amino pyrrolopyrimidine nucleotides with enzymes catalyzing different steps in the reaction sequence leading to the incorporation of amino acids into polypeptides has been studied. None of the analogue nucleotides could function as

1. Toyocamycin, in low concentrations, completely inhibits 28-S and 18-S RNA synthesis; it permits, however, the synthesis of a normally methylated 45-S RNA that accumulates in the cells' nucleoli. This RNA contains toyocamycin. The cells resume rRNA

Within 3 hr after the intraperitoneal administration of hydrocortisone to female rats, a new leucine-accepting tRNA and a new leucyl-tRNA synthetase activity appear in the liver cytosol. The new isoaccepting tRNA can be acylated only with the synthet
