- An apparently novel human plasma and urinary protein of low molecular weight was isolated from several highly purified preparations of protein HC by gel chromatography and high voltage electrophoresis with a yield of about 8 mg/g. The protein has a molecular weight of about 20,000, neutral electrophoretic mobility at pH 6.5 and a high content of half-cystine. It is associated with a yellow-brown chromophore like protein HC and could be demonstrated in all investigated preparations of isolated human, rabbit and guinea-pig protein HC and alpha 1-microglobulin.

Ribonucleotides are not channeled into DNA in permeabilized mammalian cells

Journal article (peer-reviewed)abstract
- Reddy and Pardee earlier reported that permeabilized CHEF/18 cells (J. Biol. Chem 257, 12526) or soluble extracts from such cells (Cell 32, 443) under the proper conditions preferentially incorporated a labeled ribonucleotide (CDP) into DNA without dilution by an excess of non-labeled dCTP, suggesting channeling of ribonucleotides into DNA by a multiprotein complex. Here we present results suggesting that in these experiments CDP was incorporated into RNA and not into DNA.
